Today we learned more about working together as a team in math class, and practiced some challenging
problems to build up our brains. Recent research shows that exercising and challenging your brain, like
with difficult math problems, actually grows brain cells. It strengthens and multiplies the connection in
your brain, so tasks that were once difficult get easier.
Directions for questions 1–3: Write how many squares are shown.

Quick Look
Today you and your team worked on problems that included extraneous data. That is, data that isn’t
needed to answer the math question. You practiced focusing on and picking out the data that is needed.
You also talked about other distractions that can get in the way of doing math, like loud noise, text
messages or email, trying to do many things at once, and even daydreaming or “going on vacation”
and thinking about stuff other than math. Here is an example of working through a problem that has
too much information.

Today you and your team completed problems that were missing parts. Every math word problem has three parts: the situation, the math data, and the question. You figured out which parts were missing and finished them in in a way that made sense given the information you had. You and your team also talked about times when you or a teammate is on a “bad vacation” and is angry or frustrated. You thought about ways to stop and stay cool and then come back to your team and math.
Here is an example of finishing a problem that is missing parts.

Quick Look
Mental math is a way to think about parts of numbers to make it easier to add, subtract, multiply, and
divide in our heads.
We can use basic math facts to do problems in our heads.
4,000 ÷ 80 = ?
I know 40 ÷ 8 = 5, so 80
4,000the answer is 5 × 10 or 50.
We can also break apart numbers in a math problem and use the distributive property to find the product.
18 × 5 = ?
I can think of this problem as (10 + 8) × 5, so that is 10 × 5 + 8 × 5 or 90.
And if we have to divide by 5, we can think of it as dividing by 10 then multiplying by 2. It looks like this:
530 ÷ 5 = ?
I can think of ÷ 5 as ÷ 10 × 2. So, 530 ÷ 10 × 2 = 53 × 2 or 106.

Quick Look
In everyday life, sometimes we need an exact answer and sometimes we can just estimate with an
informed guess. For example, figuring out how long two loads of laundry will take might only need an
estimate, but figuring out how much you owe for a phone bill might need to be exact.
In this lesson, you thought about different situations and decided where an estimated answer was good
enough, then practiced rounding and using compatible numbers when estimating.
For example, to estimate 5,793 × 23, you could round the numbers and get 6,000 × 20 = 12,000.
To estimate 4,326 ÷ 91, you could substitute compatible numbers and get 4,500 ÷ 90 = 50.
Directions for questions 1–3: Look at the following problems. Would you need an exact answer? Would
an estimate be enough? Explain.
1) The Brown’s have cats. They feed each cat about pound of food each day. About how much
cat food should the Brown’s purchase each month?
2) May-Lee and her friends compete in the 400-meter relay race. At their last track meet, the times for
each runner in the relay were minutes, minutes, minutes, and minutes. What was
their total time for the relay race?
3) The French club held an end of the year picnic. pizzas were ordered for students. If each
pizza is cut into 8 slices, can each student have at least three slices?

In this lesson, you practiced long division with remainders. Remainders can be shown as a whole
number, a fraction, or a decimal. One of the three ways might be most appropriate for a particular
situation. Here is an example from class:
68 teams raised $526,004 for a charity walk. On average, how much money did each team raise?
Because this problem involves money amounts, using a decimal is the best way to show this quotient:
The average amount of money raised by each team was $7,735.35.

Today we learned to estimate with decimals. For example:
Estimate 630.346 × 0.44685.
One possible estimate could be 600 × 0.5 = 300.
Even though 0.44685 rounds down to 0, it is closer to 0.5 than 0 on the number line. Rounding down to
0 would give a product of 0, which is not close to the answer. In this case, using a compatible number
gives a better estimate.

Today we learned to solve complex, real life problems involving decimals. It is helpful to make sense of
the problem, figure out what it is asking, and make a plan before solving the problem. For example:
Belinda is making granola bars for a group trip. She wants to make enough for the 62 people on the trip to
each have 1 bar. How many cups of oats does she need to make enough bars?
Granola Bar Recipe
34
1 cups of oats
14 ounces of condensed milk 1.5 tablespoons of butter 1.5 cups of chocolate chips makes 1 sheet of 24 bars
What’s going on in the problem?
Belinda is making granola bars for a certain number of people on a trip. She has a recipe for the bars.
What’s the question?
How many cups of oats does she need to make enough bars for the trip?
What do I need to do?
Divide the number of people by the amount 1 batch makes to find how many batches to make.
Multiply the amount of oats for 1 batch by the number of batches to find the total.
62 people/granola bars needed ÷ 24 bars per batch = 2.583 batches, or 3 batches needed.
3 batches × 3.25 cups of oats per batch = 9.75 cups of oats needed in all.

Today we learned how to find the least common multiple (LCM) of two numbers. The LCM is the smallest
number that is a multiple of two or more numbers. Here are two ways to find the LCM of 4 and 10:
Listing Multiples:
4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
10: 10, 20, 30, 40
Some common multiples are 20 and 40. 20 is less than 40, so 20 is the LCM.
Prime Factorization:
4 = 2 × 2
10 = 2 × 5
LCM = 2 × 2 × 5 = 20
To find the LCM, multiply each factor the most times it appears in either 4 or 10. 2 appears twice at the
most and 5 appears once. So we multiply two 2s and one 5 to find the LCM.
Directions for questions 1–6: Find the least common multiple (LCM) for each pair of numbers.

Today we used multiples and factors to solve real-world math problems. For example, we can solve the
following problem.
Henry invited 20 of his classmates to his party. He wants to purchase bottles of water and can sodas. The
bottles of water are sold in cases of 18. The can sodas are sold in cases of 12. If Henry wants to buy the
same number of bottles of water and can sodas, what is the least number of cases of water and cases of
soda he can purchase?
1) Identify the useful information.
• 18 bottles of water per case
• 12 cans of soda per case
2) Do we need to find multiples or factors?
• Henry will buy multiple cases of water and soda to get equal amounts, that means we will find the
least common multiple, or LCM.
3) Finally, solve the problem.
• 18: 18, 36, 54, 72…
• 12: 12, 24, 36…
• Henry can buy 2 cases of water and 3 cases of soda to get 36 bottles of each.

boxes. She bought the least number possible to stay within her class party budget. How many large
pizzas did she purchase? How many packages of juice?

8) They could form 5 teams.
Possible explanation: I would use the GCF to help me solve the problem because I am dividing the 8
sprinters and 12 long-distance runners into smaller teams. I would list the prime factorization of each
number, then find the common numbers in each to find the GCF. The GCF of 8 and 12 is 4, so if
every team has 4 members, there are 8 ÷ 4 = 2 sprinter teams, and 12 ÷ 4 = 3 long distance teams.
That’s 5 teams in all.

Today we learned to apply positive and negative integers to real-world situations. Integers are positive
whole numbers, negative whole numbers, and zero. Integers cannot be fractions or decimals.
For example, temperatures can be 0, above zero or below zero. A temperature of 3 below zero is the
integer –3.
We also wrote opposite integers. Opposite integers are integers that are the same distance from 0 but on
the other side of the number line. So the opposite of –7 is 7 or
+7.

Today we learned how to plot and label a given point, name the location of a plotted point, and determine
what quadrant a point belongs in by looking at the signs of the coordinates in an ordered pair.
To plot point C at (–7, 5):
1) Start at the origin. The x-coordinate is negative,
so we move 7 left along the x-axis.
2) The y-coordinate is positive, so we move 5 up.
3) Label the point as C.
To locate point B:
1) Draw a line or trace with your finger from the point to the
x-axis to find the x-coordinate. Point B crosses the x-axis at 6. 2) Draw a line or trace with your finger from the point to the
y-axis to find the y-coordinate. Point B crosses the y-axis at –6.
3) So point B is located at the ordered pair (6, –6)
Naming the quadrant:
Remember, there is a pattern to the quadrants on the coordinate
plane. The point (–8,
–3) is always located in Quadrant III because
it has both a negative x-coordinate and a negative y-coordinate.

Today we applied our knowledge of plotting and locating points on a coordinate plane to identify and
create geometric shapes.
For example, we know these coordinates are three of the vertices of a square: E (4, 3) F (–4, 3)
G (–4,
–5).What is the missing coordinate for point H?
First, plot the known points on the coordinate plane. We know a square has four equal sides; therefore,
the missing point must align with point E and point G making the ordered pair for point H (4, –5).
To double check that we have created a square, we can count the units along each side to make
sure all sides are equal.

For this figure, the x-axis is the line of symmetry. Point E is opposite point A; they have the same
x-coordinates, but opposite y-coordinates. Similarly, point D is opposite point B. They are both at 2 on the
x-axis, but point B is at 3 and point D is at –3 on the y-axis.
We can find the length of side AE by finding the distance between point E and the x-axis, point A and the

Today we learned to write ratios. A ratio is a comparison of 2 related quantities with the same or different
units of measure.
Let’s write a ratio for this problem:
There are 35 cars and 5 trucks in the parking lot.
Compare the number of cars to the number of trucks in the parking lot.
We can write the ratio three ways: 5
35 35:5, 35 to 5.
We can also write it in simplest form: 1
7, 7:1, 7 to 1.
So for every 7 cars in the parking lot, there is 1 truck.
This is a part-to-part comparison because it compares part of the vehicles, the cars, to another part of the
vehicles, the trucks.

Quick Look
Today we learned to find equivalent ratios. Equivalent ratios are two or more ratios that describe the
same comparison. You can find equivalent ratios the same way you find equivalent fractions—
multiply or divide both parts of the ratio by the same number. One way to find equivalent ratios is to
use a ratio table.
Watermelons for Picnic
number of guests
number of watermelons
5 2
10 4
8
Ratio tables are also helpful to compare two ratios:
Watermelons for Picnic Watermelons for Brunch
number of guests
number of watermelons
number
of guests number of
watermelons
5 2 4 1
10 4 8 2
20 8 20 5
By looking at the table we can see that if there are 20 guests, you will need more watermelons for the
picnic than the brunch. You can also see that if there are 2 watermelons, you will feed more guests with it
at the brunch than at the picnic.
× 2 × 2
How many guests would
be at the picnic if there
are 8 watermelons?
When there are 4 × 2 = 8 watermelons, then there are 10 × 2 = 20 guests.

Today we learned to write rates and unit rates. Rates are a type of ratio that compares two different
units of measure. Unit rates are a type of rate that compares a quantity to 1 unit of another measure.
For example:
Leslie pays $2.68 for every 4 pounds of bananas.
The rate: pounds 4
$2.68 or $2.68 for every 4 pounds.
To find the unit rate, or the cost for 1 pound, we divide parts of the rate by 4:

Today we learned how to compare rates. For example:
It costs $5.49 for a 28 ounce container of peanut butter, but it costs Jen
$0.90 to make 4 ounces of peanut butter. Which peanut butter is cheaper?
To compare rates, find an equivalent rate so that one of the units in both of the rates has the same
quantity. You can use common factors and common multiples to compare. In this example, 4 is the GCF
of 4 and 28.
Store-bought Homemade
$0.80 4 ounces $0.60 4 ounces
$5.60 28 ounces
$0.80 for 4 ounces > $0.60 for 4 ounces. Jen can make her own peanut butter for less than she can buy
the store-bought kind.
You can always use unit rates to compare because one of the units will have a quantity of 1. Let’s find
how much 1 ounce of peanut butter costs for each type.
Store-bought

Today we learned to use the Find a Pattern Strategy to solve a word problem. For example:
Ameen is trying to shorten the time it takes to do his chores. In week one, he finished them in
194 minutes. In week two, he finished them in 190 minutes. In week three, he finished them in
186 minutes. If he keeps going like this, by how many fewer minutes will it take him to do chores
in week seven than in week one?
Week one two three four five six seven
Minutes
to do
Chores
194 190 186 182 178 174 170
If the problem looks like it has a pattern, create a table for the given information. At least 3 pieces of
information are needed to determine a pattern. In this problem, the pattern is that Ameen shortens his
time each week by 4 minutes. Next, fill in the table to find how long it takes Ameen to do his chores in
week seven, 170 minutes. Finally, solve. It took him 194 minutes to do his chores on week one. The
difference in time between these two weeks is 194 – 170 = 24 minutes. So, Ameen takes 24 fewer
minutes to complete his chores in week seven than week one.

We represented the equivalent ratios from the chart as points

an equivalent ratio for 2 drops of blue to 3 drops of yellow.
We know that 6 drops of blue and 9 drops of yellow is an
equivalent ratio because the line passes through the point (6, 9).
We also know that 3 drops of blue and 4 drops of yellow is not

Today we learned to find the percent of a number. Here’s what that looks like!
15% of 30 is 4.5 because 0.15 × 30 = 4.5.
A percent is a ratio of a number out of 100, so 15% = 100

We also learned to find the whole when given a part and percent. We can use equivalent ratios to help
solve. Here’s an example!
Ms. Lin has collected 75% of the sixth’s graders permission slips. If she has 63 slips,
how many sixth graders are there?
If 63 represents 75% of the sixth graders, then 63 ÷ 3 = 21 makes 75% ÷ 3 = 25% of the sixth graders.
25% × 4 = 100%, so there are 21 × 4 = 84 sixth graders.

Today we learned the Guess and Check strategy to solve problems. We made educated guesses to help
us prove the problem. An educated guess is a guess based on information you have. It is not a random
guess. Here’s an example!
Scarlett spent $62.06 on three different items at the home improvement store. What did she buy?
We know that she did not buy the towel bar because its price ends in 9 cents. There is not another item or
items that would add to give $0.06.
Now we make our best guesses and keep track of them until we find the correct combination:
light bulb + shower head + window screen = $63.90
doorbell + shower head + window screen = $62.06
So Scarlett bought a doorbell, showerhead, and window screen.

Today we learned about exponents. Exponents are a way to rewrite expressions that multiply the same
number or variable more than once. For example, we can rewrite 4 • 4 • 4 • 4 • 4 as 45 because we are
using 4 as a factor 5 times. We also see exponents in some formulas.
We find the area of a square by multiplying length times width.
On a square, the length and the width are the same size. So our formula is A = s • s. That’s

Today we used our knowledge of the Order of Operations and problem solving to answer real-world math
problems. First, we found the key words and numbers in the math stories and situations. Then, we turned
those words and numbers into numeric expressions. Finally, we used the Order of Operations to evaluate
the numeric expressions and answer the questions.
Here’s an example:
Gerald’s Toy Factory makes 3 colors of teddy bears: brown, tan, and yellow. Each type of teddy
bear uses 3 yards of fabric. The factory can create 50 teddy bears each hour. They make brown
teddy bears for 3 hours each day, tan teddy bears for 4 hours each day, and yellow teddy bears
for 2 hours each day. So how much fabric does Gerald’s Toy Factory use in a day to create
teddy bears?
The important information in the problem is highlighted in yellow. The question we have to answer is
highlighted in green. Let’s write a numeric expression to help us.
Teddy bears created each day: 50 hour
bearsteddy • (3 hours + 4 hours + 2 hours) • 3
bearteddy
fabric of yards
50 hour
bearsteddy • 9 hours • 3
bearteddy
fabric of yards
450 teddy bears • 3 bearteddy
fabric of yards = 1,350 yards of fabric each day.
No matter what color teddy bear is being made, Gerald’s Toy Factory makes 50 teddy bears each hour.
So we found the total hours that the factory makes teddy bears, multiplied that by the rate of teddy bears
created each hour. Then we multiplied that by the ratio of fabric needed to create each bear. We used the
Order of Operations to do the work in the parentheses first, then to multiply from left to right.

Today we wrote an algebraic expression to describe a real-world situation. Then, we evaluated the
expression at a specific value. Here’s an example!
Sim made 78 scarves. He sold t scarves on Saturday and 30 scarves on Sunday.
Write an expression to describe how many scarves Sim has left.
78 – t – 30 or 78 – (t + 30)
Sim had 78 scarves. If he sold 20 on Saturday and t on Sunday, he sold 20 + t scarves in all. So to find
how many he had left, subtract the scarves he sold in all from the total amount of scarves he made.
Evaluate the expression when t = 45
If t = 45, that means he sold 45 scarves on Saturday. Replace t with 45 and evaluate using the
Order of Operations.
78 – (t + 30)
78 – (45 + 30)
78 – 75 = 3; Sim has 3 scarves left.

Today we used the Solve a Simpler Problem strategy to solve problems. Here’s an example!
Oli sold 124 cups of lemonade on a Sunday. Jake sold 1.5 times more cups of lemonade then Oli.
Rue sold 1.86 times fewer cups than Jake. How many cups did Rue sell?
Three people are selling lemonade. We need to determine how many cups Rue sold. Let’s use simpler
numbers to make this problem easier.
Oli sold 5 cups of lemonade on a Sunday. Jake sold 4 times more cups of lemonade than Oli.
Rue sold 2 times fewer cups than Jake. How many cups did Rue sell?
Here’s the solution with simpler numbers:
5 • 4 = 20 20 ÷ 2 = 10
Now, substitute the real numbers into the expressions you wrote:
124 • 1.5 = 186 86 ÷ 1.86 = 100
So Rue sold 100 cups of lemonade.

Here’s an example.
Is (5x + x) + 5x2 + 3x + 12 equivalent to 9x + 5x
2 + 12?
Yes, because when x = 2, both expressions name the same number.
(5 • 2 + 2) + 5 • 22 + 3 • 2 + 12 = 50 9 • 2 + 5 • 2
2 + 12 = 50
Also because when you use the Properties of Addition to combine like terms,
(5x + x) + 5x2 + 3x + 12 simplifies to 9x + 5x
2 + 12.

Quick Look
Today we identified four Properties of Multiplication: Commutative, Associative, Identity, and Zero. Here are some examples of how we used them: By changing the order and grouping of the numbers and variables, it is easier to simplify this expression. 30 • (y • 5) • y = 30 • y • 5 • y Associative Property = 30 • 5 • y • y Commutative Property = 150y
2
y • y = y2 just like 5 • 5 = 5
2 and 2 cm • 2 cm = 4 cm

We can use the properties to identify the value of variables j and k in the expressions below.
65j = 65 We know j = 1 because of the Identity Property of Multiplication—any number times 1 is that
same number.
4 + 5 • k = 4 We know k = 0 because of the Zero Property of Multiplication—any number times 0 equals 0.

Today we evaluated and re-wrote expressions to determine whether two expressions are equivalent.
Here’s an example!
Is 5x + 6x2 equivalent to x(5 + 6x)?
Yes, because when x = 2, both expressions have a value of 34.
5 • 2 + 6 • 22 = 34 2(5 + 6 • 2) = 34
Also, we can use the Properties of Multiplication to rewrite or simplify one expression to see if it can be
rewritten as the second. Here we used the Distributive Property to rewrite the second expression to look
like the first expression. This tells us that the two expressions are equivalent.

represent equations; they are only balanced when each side has an equal value.
To balance this scale, remove 3 unit tiles from the right side of the scale.
The equation, 4 = 7 – 3, show how we balanced the scale. The balanced scale is an equation.
This scale is already balanced but we don’t know the value of the variable, s.

7 = x
6 + 5
7 = 3

7 = 7
x = 3 is the solution for 7 = x
6 + 5 because it kept both sides of the expression balanced.
Is x = 3 a solution for 8x = 27.75 – 2.25?
8x = 27.75 – 2.25

x = 3 is not a solution for 8x = 27.75 – 2.25 because it does not keep both sides of the expression balanced.

Today we used images to help us solve equations related to area and perimeter. Here’s an example!
Ms. Sue knows that the perimeter of the triangle is 38 feet. Here is her work:
P = f + g + h
38 = 11 + g + 9
How can the image help Ms. Sue find the value of g?
Perimeter is the distance around the triangle, so we add all the side’s lengths of the triangle. We can see
in the image that g must equal 8, it is the missing side length from the equation to find perimeter.
Both sides describe the perimeter—they are just expressed in two different ways.
After determining the value of g, be sure to check to make sure both sides of the equation are still balanced:
8 + 11 + 9 = 28
28 = 28 g = 11 is the solution.

Today we discussed inverse operations and we used them to solve equations equal to 1 or 0.
For example, addition and subtraction are inverse operations:
u + 25 = 0 r – 18 = 0
– 25 – 25 + 18 + 18
u = –25 r = 18
Also, multiplication and division are inverse operations:
3v = 1 13
q = 1
3v ÷ 3 = 1 ÷ 3 13 • 13
q = 1 • 13
v = 3
1 q = 13
Using the inverse operation to solve these simple equations helped us isolate the variable on one side of
the equation. This is similar to moving the unit blocks from each side of a scale to get the variable tile by
itself. Just like with the scale, when whatever we do to one side of the equation, we must do the same to
the other side to keep the equation balanced.

Today we solved addition and subtraction equations using inverse operations. In these equations, we
used the inverse operation to find the solution for each variable. We made sure that whatever we added
to or subtracted from one side of the equation that we did the same to the other side. This keeps the
equation balanced, like a scale.
For example, let’s solve the equation: y + 1,382 = 2,400
We can estimate first to see about what our solution will be.
y + 1,400 = 2,400
1,000 + 1,400 = 2,400, so y is about equal to 1,000.
When we solve the equation we use the inverse operation to help us:
y + 1,382 = 2,400
– 1,382 – 1,382
y = 1,018
We should check to see if our solution is correct by substituting it into the original equation.
y + 1,382 = 2,400
1,018 + 1,382 = 2,400
2,400 = 2,400
We know our solution is correct because the equation remains balanced!

Today we solved multiplication and division equations using inverse operations.
For example, let’s solve the equation: y • 25 = 450.
We can estimate first to see what a reasonable solution will be.
y • 25 = 50 I know that 2 • 25 = 50, so 20 • 25 = 500. That means y is about equal to 25.
Next we solve the actual problem.
y • 25 = 450
25 25
y = 18
Our solution is close to our estimate! But let’s check for sure by substituting our solution into the original equation.

Today we answered real-world problems by solving addition, subtraction, multiplication, and division
equations. We identified the variable in each equation as representing the question we have to answer.
So solving the equation for the variable also answered the question!
For example:
Sara is filling containers with water from the cooler. Each container holds 2
1 a gallon of water.
If the cooler holds 25 ½ gallons, then how many containers can Sara fill?
Let’s use this equation to answer the question in the math story! 2
1c = 25

Each container holds 2
1 gallon of water, that’s multiplication! The variable, c, represents the number of
containers. If we solve the equation for c, then we can see how many containers Sara can fill!
Estimate:
1 gallon equals 2 half gallons.
So 25 gallons would be 50
half gallons.

Erik scored several points in today’s game. Yesterday, he scored 25 points in the game.
He made a total of 44 points in the two games. How many points did Erik score today?
a. m • 25 = 44
The words ‘and’ and ‘total’ tell me the problem is about multiplication, Choice a is addition,
so choice a is not correct.
b. 25 + m = 44
Choice b shows adding 25 to today’s score and equaling 44. It is correct!
c. m = 44 + 25
Erik made a total of 44 points, so 44 should be alone on one side of the equation.

b • 14 = $343
b = $24.50
The words ‘each’ and ‘in all’ mean to multiply. We multiplied 14 tickets by the cost of each ticket, b,

Today we learned about the difference between equations and inequalities and identified and wrote
inequalities. Here’s an example!
The books weigh more than 4 pounds.
This scale shows that the weight of the books
is greater than 4 pounds, we can write it as
an inequality.
If b = weight of the books, then:
b > 4 (b is greater than 4)
4 < b (4 is less than b)
Both inequalities are correct; the weight of the
books is greater than 4 pounds or 4 pounds is
less than the weight of the books.

Today we graphed inequalities on number lines. For example, let’s represent g < 5 + 2 on a number line.
First, simplify the right side of the inequality:
5 + 2 = 7, so g < 7.
Second, graph the inequality:
Use an open circle to indicate that g is not equal to 7.
Going left on the number line shows less than.
g is less than 7, so we shade everything to the left of 7.
We shade the arrow to show that numbers beyond –10 are also less than 7.
Finally, what are some solutions to the inequality?
g = –3 is a solution to the inequality.
It is in the shaded region of the number line and it keeps the inequality true.
g < 7

Quick Look
Today we found solutions to inequalities. Let’s find three solutions to this inequality.
63 – k < 40
The difference between 63 and k is less than 40. That means we need to subtract a number from
63 that will give us a difference that is less than 40.
Let’s try when k = 30
63 – k < 40
63 – 30 < 40
33 < 40 True
k = 30 is a solution because it keeps the inequality true. That means if we subtract a number
larger than 30 from 63, it will also keep the inequality true. What if k = 40 or k = 63?
63 – k < 40 63 – k < 40
63 – 40 < 40 63 – 43 < 40
23 < 40 20 < 40
True True
So three solutions to the inequality are 30, 40, and 43.

Today we wrote inequalities to represent real-life situations. We also found solutions to the inequalities to
answer questions about the real-life situation. Here’s an example!
Leo’s goal is to lose more than 10 pounds.
If p = the number of pounds Leo wants to lose, then p > 10.
If Leo lost 7 pounds the first month and 5 pounds the second month,
would he meet his goal?
If p = 7 + 5,
7 + 5 > 10
12 > 10
If Leo lost 7 + 5 = 12 pounds, he would meet his goal
because 12 pounds is greater than 10 pounds.

Today we identified the independent and dependent variables in math tables and real-world math
situations. We also explained the relationship between the variables; did they both increase? Both
decrease? Did one increase while the other decreased?
Here’s an example!
In this situation, the room temperature increases as the number of people in the room increases. You
could also say that the room temperature decreases as the number of people in the room decreases. The
room temperature depends on the number of people in the room, so the room temperature is the
dependent variable. The number of people in the room affects the room temperature, so it is the
independent variable.

Today we identified independent and dependent variables. Here’s an example!
Dan is determining the distance he travels when he walks 2 miles per hour.
d = 2t d is the distance and t is the time he has walked in hours.
The value of d depends on what you multiply 2 by. That means the dependent variable is d, and the
independent variable is t. The distance depends of the amount of time Dan has walked.
We also completed charts to show how the dependent variable is affected by the independent variable.
This chart shows different values for time and distance. To complete a chart, select a value for the

Today we wrote equations for real-world situations involving area, perimeter, and volume. For example:
Nevaeh is choosing between three different side lengths for a square table.
How do the different lengths change the total area?
To find the area of a square, multiply length
by width. That’s A = s2. Let’s use a chart to
track how changing the side length of the
table changes the total area.
The independent variable is the side length, and the dependent variable is the area.
Nevaeh will choose a side length for her table that gives the area she wants.
Here are some geometry formulas that may help you write equations for these problems.
Area: A = l • w A = s2
Volume: V = B • h V = l • w • h
Perimeter (square): P = s + s + s + s P = 4s
Perimeter (rectangle): P = l + l + w + w P = 2l + 2w

Today we wrote equations and graphed data to describe the relationship between independent and
dependent variables. Here’s an example!
The table shows us original and sale prices. As the original cost decreases, the sale price also
decreases. The sale price depends on the original price, so the sale price is the dependent variable and
the original price is the independent variable.
On the graph:
x is always the independent variable, and
y is always the dependent variable.
All points on the line represent what the sale
price would be for any original price.
We can use the data from the table or graph
to create an equation.
The pattern is: subtract $2 from the original price
to get the sale price.
That’s y = x – 2.

Today we learned that converting between measurements is one type of linear relationship. We used the unit rate to write a linear equation for the relationship and to create a chart that showed different measurements in the relationship. We also graphed the relationship using information from our chart. Whenever we converted between two measurements, like inches and centimeters, we saw that as one measure got larger, so did the second. When we graphed it, we saw the linear relationship.
For example:
Did you know that male lions patrol a vast territory to protect their pride, or family? Normally, this distance covers 100 square miles, or 259 square kilometers.
We can write a unit rate to describe the relationship between the two units of measure:
259 sq km = 2.59 sq km 100 sq mi 1 sq mi
So 1 square mile equals 2.59 square kilometers.
Knowing the unit rate can help us write an equation to represent the relationship. To get from square miles to square kilometers, multiply by 2.59. So if k stands for square kilometers and m stands for square miles, then k = 2.59m.
Now that we know the equation, we can easily find missing information. If a park rests on 500 square kilometers, how many square miles is that? Use the equation to find out! Substitute 500 for k and solve for m.
k = 2.59m 500 = 2.59m 193.05 = m
The park is 193.05 square miles!

Today we solved multiple-step problems about real-world math situations. We used our knowledge of converting measures, finding unit rates, comparing rates, and even geometric formulas to answer real-world questions. In these questions we converted and combined measures of length, weight, and capacity. We worked with both customary and metric units of measurement.
For example:
Aiden bought chips and salsa to serve at his party. He bought 10 bags of chips that each contained 1 pound of chips. He also bought a 1 gallon jar of salsa. Does Aiden have enough salsa to serve 6 fluid ounces to each of his 20 party guests?
He bought salsa in a gallon jar but wants to share it in servings of 6 fluid ounces. Let’s compare the fluid ounces he bought to the fluid ounces he needs for the party:
Salsa bought: 1 gal • gal 1
oz fl 128 = 128 fl oz
Salsa needed: 20 guests • 6 fl oz per guest = 120 fl oz
Aiden needs 120 fluid ounces of salsa to serve each of his guests. He bought 128 fluid ounces of salsa, so he will have enough for the party!

Today we examined the properties of polygons. We explored different ways polygons could be identified and categorized. We identified polygons based on sight and description. We also described polygons in very specific detail. Given coordinates, we even drew polygons and identified them as well.
We used some of the following vocabulary when describing polygons:
Polygon – a two-dimensional, closed figure made up of 3 or more line segments
Equilateral – all sides are the same length (congruent)
Parallel – line segments that do not intersect because they are always the same distance apart
Perpendicular – two lines that intersect at right angles
Scalene – a triangle with no congruent sides
Isosceles – a polygon with two congruent sides, usually a triangle or trapezoid
Acute – an angle whose measure is greater than 0 and less than 90 degrees
Obtuse – an angle whose measure is greater than 90 and less than 180 degrees
Right – an angle whose measure is exactly 90 degrees
For example, we could describe this polygon:
This polygon has four sides and four angles, meaning it is a quadrilateral. This quadrilateral has exactly one set of parallel sides, making it a trapezoid. Furthermore, the two sides that are not parallel are congruent. So this is an isosceles trapezoid.

Today we learned how to find the area of rectangles and triangles. The area is the space inside a closed
figure. To find the area of a rectangle, we multiply the length by the width: A = l • w. We learned that a
rectangle can be divided in half to create two triangles. That means we find the area of a triangle by
dividing the area of a rectangle in half: A = 2

A = 2

Today we learned how to find the area of special quadrilaterals. We broke apart and rearranged
parallelograms, trapezoids, and rhombi to create rectangles and triangles. We used the formulas for area
of a rectangle and a triangle to help us find the total area of the special quadrilaterals. We also used the
formula for area of a rectangle to help us find the formula for area of a parallelogram.
Here’s what we did!
We broke apart a triangle from the parallelogram and rearranged it to create a rectangle. It’s easy to find
the area of a rectangle.
Area = l • w
A = 12 km • 3.5 km = 42 km²

Today we broke complex shapes into rectangles and triangles so we could easily find the area of the
shape. Sometimes, there are multiple ways to divide a shape up to make easier shapes, but the total area
is always the same. Here’s an example!
We can divide this polygon into one rectangle and two triangles. Then we can find the area of
each shape.
Area of the rectangle: A = l • w
A = 7 units • 6 units = 42 units²
Area of the top triangle: A = 2
1b • h
A = 2
1• 2 units • 5 units = 5 units²
Area of the bottom triangle: A =2
1b • h
A = 2
1• 2 units • 5 units = 5 units²
Now add to find the total area:
42 units² + 5 units² + 5 units² = 52 units² So the area of the polygon is 52 units².

Today we solved multiple-step problems about real-world situations involving area. We investigated math stories for necessary information and eliminated extraneous information. We used the formulas for area of a rectangle and a triangle to help us find the total area. For some problems, it was helpful to sketch a model of the situation in the word problem. Here is an example!
A store sells two types of wrapping paper. Type A i s a solid color. It has 4 rolls per package and each roll is 29 inches by 59 inches. Type B is very glossy and has lots of graphics.
It has a single roll and is 35 inches by 197 inches . Which type gives you more wrapping paper?
First, find the area of Type A by multiplying the length and width of a single roll. A = l • w A = 29 in. • 59 in. A = 1,711 in²
Then, multiply the area of the single roll of Type A by 4, because there are 4 rolls in a package. A = 1,711 in.² • 4 = 6,844 in.²
Next, find the area of Type B. A = l • w A = 35 in. • 197 in. A = 6,895 in.²
6,844 in. 2 < 6,895 in. 2, so Type B gives you more wrapping paper!

Today we identified statistical questions, numerical data, and categorical data. Here’s an example!
Mitch wanted to know more about the marching band at school. He made a list of survey questions to ask:
a. How many hours do you practice your instrument at home?
b. What instrument do you play?
c. How many hours did the band practice at school this week?
d. What percentage of middle schools in the U.S. have marching bands?
Questions A and B are statistical questions because the responses will tell Mitch more about the
marching band. They will also have variability, or a range of different answers, because students practice
different number of hours at home and play different instruments.
Question A will give categorical data because people will respond with different instruments.
They may respond with piccolo, clarinet, tuba, or cymbals!
Question B will give numerical data because people will responds with different numbers of
hours. They may respond with 0, 3.5, or 10 hours!
Question C is not a statistical question. All the responses will be the same number of hours, so there will
be no variability in the data.
Question D is not a statistical question about the marching band at school. The responses will all be the
same and will not give more information about the school marching band.

Today we solved problems involving variability. Here’s an example!
Anastasia is taking her car for an emissions test. Carbon dioxide levels in her car emissions can be
between 13% and 16% and oxygen levels can be between 0.3% and 1.5%.
Will the data for the cars that pass the test have more variability in the carbon dioxide levels or in
the oxygen levels? How do we know?
There will be greater variability in the carbon dioxide levels because they can be between 13% and 16%,
or vary by 3 percentage points. The oxygen levels can only be between 0.3% and 1.5%, so they only vary
by 1.2 percentage points.

We can draw different conclusions from the dot plot such as: the most frequent weight for a newborn
kitten on Alicia’s farm is 3.5 ounces. This graph does not tell us everything we may want to know about

Denisha’s Heart Rate (in beats per minute) on Swings
resting 2 minutes 4 minutes 6 minutes 1 minute after stop
77 82 100 112 90
This is a line graph because it shows Denisha’s heart rate over time. At any point during this activity,
Denisha has a heart rate.
Each dot represents one piece of data and line segments connect the dots. We can guess that Denisha’s
heart rate was about 80 beats per minute at 1 minute.
Denisha’s heart rate changed the most between 6 minutes after starting the exercise and 1 minute after
stopping.
The trend is that Denisha’s heart rate increases when she started swinging and then decreases after she
stops swinging at 6 minutes.

Today we described the shape of data distributions, that is, what the whole set of data looks like when
graphed. We looked at data displayed in histograms and dot plots. We described the shape as
symmetric, skewed left or right and as having clusters, peaks, or gaps. We also answered questions
directly based on the shape of the data.
We used the following vocabulary about the distribution of data displayed in dot plots and histograms:
Skew – A graph is skewed if it is more developed on one side or in one direction than another. Skewed
graphs are not symmetrical and are skewed left or right depending on the direction of the “tail”.
The “tail” of a graph represents the outlier data.
Symmetric – A distribution of data is symmetric if there is a center of the data and the shape of the data
to the left and right of that center mirror each other.
Gap – Gaps are large spaces in the data or intervals where there is no data.
Peaks – Peaks in the data look like the top of a hill that slopes on either side. Peaks are values with a
higher frequency than their neighbors.
Cluster – Clusters are “clumps” of data separated by gaps.
For example,
We can describe the distribution of data on this graph by saying it is approximately symmetrical.
The data starts low on the left, rises in the center, and descends on the right. The peak at 70-74 is
not in the center, which prevents this from being truly symmetrical. Also, this data has no gaps or clusters.

Today we made box-and-whisker plots. These plots show the data distribution divided into quartiles, or
quarters, of the full set of data. We also identified the extremes, quartiles, range, interquartile range, and
median. We used the following vocabulary when we constructed the box-and-whisker plots:
Extreme – The greatest and least numbers in a set of data are the upper and lower extremes.
Range – The range is the difference between the greatest and least values in a set of data. The range
can also be given as an interval.
Median – The median is a number arrived at by counting to the middle of an ordered array of numerical data.
Quartile – The upper and lower quartiles are the medians of the upper and lower halves of the ordered
data values.
Interquartile range – The distance between the first and third quartiles is the interquartile range. This
number serves as a very useful measure of variability.
To make a box-and-whisker plot:
1) Write all the data values in ascending order.
2) Identify the upper and lower extremes.
3) Find the median of the data set.
4) Find the upper and lower quartiles.
5) Plot these numbers above a number line; box in the quartiles and draw whiskers from the
quartiles to the extremes.

Quick Look
Today we compared box plots. Box plots are an excellent way to compare data sets because the middle
of the data and the quartiles are clearly marked and easy to interpret. Today we described the shape of
the distribution and discussed what that meant in terms of the other box plots. We looked for key
differences between the box plots and answered questions based on the data.
For example, if we examine these box plots, there are several things we can deduce based on the shape.
The Regular Season box plot is approximately symmetrical but the Playoffs box plot is skewed
right. During the regular season, the all-time leaders scored about 22 points per game whereas
all-time leaders in the playoffs scored about 25 points per game. We can also see that about 50%
of the points per game scored during the playoffs was greater than 75% of the points per game
scored during the regular season.
The plots show there is a very clear difference in the number of points per game scored during different
times in the basketball season.

Today we found the mean, median, and mode of a data set. We worked with whole numbers, fractions,
and decimals. We already know how to find the median from our work with box plots. Today we learned
how to calculate the mean of a data set.
Mean = sum of data ÷ number of data items
We also found the mode, the number that occurs most, in a data set. When all numbers in a data set are
different, there is no mode. If there is more than one mode, all the most frequently occurring numbers
must be recorded. For example, in this data set; 15, 34, 49, 55, 37, 44, 48, 49, 30, 3, 55; the mean is
39.2, the median is 40.5, and the modes are 49 and 55.

Today, we examined data sets to decide whether the mean or the median is the better measure of center
in the context of the questions posed. We learned that sometimes the mean is not the best measure of
center. When outliers skew the data, the mean has a tendency to be pulled toward the extreme value,
usually much more than the median.
For example,
Last week’s high temperatures were 78, 82, 85, 84, 81, 78, and 79. The mean is the best measure of
center for this situation. The data is not affected by any outliers that could skew the mean towards an
extreme value.

Today we learned about the spread in a data set. First we chose the measure of center that represented
the data set. We learned that when the mean is the best measure of center, we find the mean absolute
deviation (MAD) for the measure of spread. We also learned that when the median is the best measure of
center, we find the interquartile range (IQR) for the measure of spread. Then we discussed what the
measure of variation tells us about the data.
To find the mean absolute deviation (MAD):
Step 1: Find the absolute value of the distance between each data value and the mean.
Step 2: Find the mean of the distances.
To find the interquartile range (IQR):
Step 1: Identify the lower and upper quartile values of the data set.
Step 2: Subtract the lower quartile from the upper quartile.
For example, this chart lists the high temperatures in a city over a two week period.
81 80 82 82 83 85 86
88 102 105 88 86 84 83
When we find the mean of the data (86.78) and the median (84.5), we see that the mean is affected by
the higher temperatures, whereas the median is less affected. Since the median is the best measure of
center, we find the interquartile range by subtracting the lower quartile from the upper quartile. So the
measure of spread is 6, which is close to zero. This tells me that the middle half of the data is consistent,
or the high temperatures are very close together.

Today we solved multiple-step problems about real-world situations involving data. We investigated math
stories for necessary information. We analyzed and determined the best measure of center for each data
set. We also analyzed what the measure of spread told us about the data set. Then we answered
questions related to the problem.
For example:
If you were shopping through an online retailer, you would examine the ratings of different companies.
You would also see what their performance has been over a period of time and how it has or has not
improved. You would also compare one retailer against another to see who has the best results. All of
these things involve looking at and analyzing data.

Quick Look
Today you learned about market research and target audiences. Businesses use market research to
help them make decisions about what items and services to offer their customers. The data they compile
from their research helps them to make better products and offer better services that will appeal to the
most people. This is important for businesses to make enough money to be profitable and to keep doing
more business.
When a business does market research they have to make sure to work with members in their target
audience to get the most helpful data to make business decisions. For example, if a company creates
office supplies, their target audience would be people who worked in and managed offices. They probably
would not want to survey children in elementary school or retired couples.
Finally, today you created a survey of questions for your new travel agency to help you do market
research about the vacation destinations and the activities that would most appeal to families to buy your
three-day Family Weekend Vacation Getaway. This week you will use the data from your survey to create
data displays and to make decisions for your travel agency business.
For your travel agency you also want to know the best way to reach new potential customers. What kind
of advertising should you do? Tonight, you will create a short survey for your customers to help you
determine what sort of advertising might be most effective.
1) Brainstorm the different ways that businesses do advertising. (Hint: Businesses use many methods to
get in touch with potential customers. Think about T.V., mail, email, and internet advertising to get
started with your list.)
PowerTeaching: i3 Level F Unit 15 Cycle 3 Lesson 1 2 © 2012 Success for All Foundation Homework Problems
2) Use your brainstorm from question 1 to create a good survey question to ask potential customers to
help you know the best possible method to advertise and reach your customers.
3) Describe the target audience for your survey question from question 2. Think about who sees
advertisements and makes decisions about purchasing vacation packages from a travel planner.
4) What kind of data will you get when you ask your survey question from question 2, categorical or
numerical? What type of data display might you use for that data? (Hint: line/dot plot, bar graph,
histogram, line graph, circle graph, or box plot)
5) You also want to know how much small businesses, like yours, typically spend on advertising each
month. Who would be the target audience for a survey question about advertising costs?
6) Write a good survey question that will help you gather data about the monthly advertising costs for a
small and new business.
7) What kind of data will you get when you ask your survey question from question 6, categorical or
numerical? What type of data display might you use for that data? (Hint: line/dot plot, bar graph,
histogram, line graph, circle graph, or box plot)

Today you continued your research as an up and coming travel planner! You used the data gathered from
the survey you created yesterday to create various data displays. You thought about the types, amount,
and variety of data you gathered to make the best decisions about which data displays you would use.
For categorical data, you had to choose between a dot plot, a circle graph, and a bar graph to best
represent your data. For numerical data, you had to choose between a line plot, a stem-and-leaf plot, a
box plot, a histogram, and a line graph to best represent your data.
For homework, you will use data concerning advertising for your travel business to make new data
displays. In the next lesson, you will use the data displays you have created to analyze your data, design
a family vacation package, and to make decisions for your new business!
Directions for questions 1–3: Use the given data to help you answer each question.
When 50 randomly chosen people in families in your community were chosen for your survey, they
were asked, “Which method of advertising do you encounter more each day: television commercials,
radio ads, magazine ads, advertisements on web pages, or billboards?” You received the following

Today you completed the analysis of the data you collected and graphed about a family weekend
vacation. You used the graphs and plots you made to show the data you collected, then you analyzed
them to decide the location of the vacation, the number of family activities it would include, and what
those activities would be.
You also created the first draft of your email blast that you will send out to potential new customers. This
email included your contact information as well as the details about your first travel package, the Family
Weekend Vacation Getaway!
