Let’s Bring LONG + LIVE + MATH to SUSD!Your Reviewer’s Guide for Carnegie Learning’s Middle School and High School Math Solutions
It’s time to scale your magic. The experience your students have with math now will make everything else possible — learning how to think, solve problems, persevere, and passionately pursue careers that challenge and reward them.
Carnegie Learning combines the market’s best math resources with a powerful “all in” passion for service. Our goal? To deliver a deeper level of blended learning. One where students are given opportunities to learn together (using printed resources or interactive eBook) and learn individually (using MATHia® Software).
So let’s get started. This Guide will walk you through the materials you received and the MSPS Review Site will let you see digital resources and MATHia (see box to the right for login info).

STEP 2
Grab the Teacher Implementation Guide. Read the frontmatter and the teacher facilitation notes.
FRONTMATTERWe invite you to familiarize yourself with our program design by reading the frontmatter of our Middle School and High School Math Solution books. This section will:
• Take you through Carnegie Learning’s philosophy and introduce you to the program.
• Take you through the progression of content through the grade-specific course. You’ll also be able to see the standards progression by grade level. To see the Arizona correlations, go towww.carnegielearning.com/scottsdale.
• Discuss how Carnegie Learning supports students as they encounter topics and the various lesson characteristics that foster student creativity and critical thinking.
FACILITATION NOTESEvery topic in the Teacher Implementation Guide contains facilitation notes. These serve to guide teachers and support them with pacing, differentiation techniques, essential questions, what to look for in student work, ELL supports, common misconceptions, and other tips.
M2-57D • TOPIC 1: Ratios
Questions to ask• What is the ratio 60 : 10 reduced? • Is your weight less on the Moon or on Earth? • One pound on the Moon is equivalent to how many pounds on Earth? • Two pounds on the Moon is equivalent to how many pounds on Earth?
Misconceptions• For Question 1, students may write the the ratios in fractional form,
resulting in the statement 60 ___ 10 1 30 ___ 5 5 90 ___ 15 . Then, they look at those “fractions” and decide to divide them, resulting in the incorrect statement 6 1 6 5 6. Remind students that part-to-part ratios are notfractions, so they cannot be divided to yield a quotient. You may wantto discourage students from displaying their part-to-part ratio work in fractional form (unless they are using proportions).
• To help clarify Ralph’s misconception, you may want to refer to Vicki and Benjamin’s age problem in Activity 1.1.
Have students work with a partner or in groups to complete Questions 3 through 5. Share the responses as a class.
Questions to ask• How is an equivalent ratio determined using division?• How is an equivalent ratio determined using multiplication?• How is an equivalent ratio determined using addition?• What is an example of an equivalent ratio that is not in the table? How
did you determine the ratio?• What is an incorrect way to use addition to determine an
equivalent ratio?
Summary A ratio table is a useful tool to represent equivalent ratios. The ratio between the cells of a column is the same for all columns. To determine equivalent ratios, you can add, subtract, multiply, or divide any column.
Activity 4.2Using Equivalent Ratio Tables
Facilitation NotesIn this activity, students use a given ratio to complete an equivalent ratio table. Then the table of values is used to answer questions in the same scenario.
Ask a student to read the introduction aloud. Have students work with a partner or in groups to complete Questions 1 through 3. Share responses as a class.

LESSON 4: A Trip to the Moon • M2-57C
Getting Started: I’m Your Density
Facilitation NotesIn this activity, students consider the pictorial representations of population density and decide which state has the greatest and least population density.
In preparation for this activity, research the population density of your state and/or city. Students will need this data for Question 2.
• US: 76 people per square mile. How does that compare?• Possible site to research density of your state: https://en.wikipedia.org/
wiki/List_of_U.S._states_by_population_density• Research distances between local landmarks or roads to help students
visualize a square mile.
Ask students to work with a partner or in groups to complete Questions 1 and 2. Post the information needed to answer Question 2 in the classroom. Share responses as a class.
SummaryPictorial representations are used to describe ratios in real-world scenarios.
Activity 4.1Introduction to Ratio Tables
Facilitation NotesIn this activity, students use the ratio of weight on Earth to weight on the Moon to solve problems. They analyze strategies used to determine equivalent ratios of weight on Earth : weight on the Moon.
Ask a student to read the introduction scenario aloud. Discuss the information as a class. Have the students review the worked example individually.
Questions to ask• Why are the values in the table considered ratios rather than rates?• Does the ratio represent a part-to-part or part-to-whole relationship?• Why does adding two ratios create a third equivalent ratio?
Have students complete Questions 1 and 2 with a partner. Then share the responses as a class.

• Does it matter what order you subtract the values to determine the slope from a table of values? Explain.
• What units are used for the first differences?• What units are used for slope?• How did you create a table to represent a linear function? Is there
another way to do this?
Summary The expression an 5 a1 1 d(n 2 1) can be rewritten as an 5 a0 1 dn, where a0 represents the y-intercept. First differences is a strategy to determine whether a table of values represents a linear function.
Activity 1.3Connecting Constant Difference, Slope, and Average Rate of Change
Facilitation NotesIn this activity, students generalize the concepts of constant difference and slope by using variable expressions for the consecutive terms. They use a table, a graph, and algebraic reasoning to demonstrate that the slope of a linear function is always equal to the constant difference of the corresponding arithmetic sequence. The average rate of change formula using function notation is introduced as another form of the slope formula.
Have a students read the introduction. Discuss as a class.As students work, look for
• Confusion related to variable expressions being used as term numbers and why they are being used instead of constants.
• Sense-making that an expression with more than one term can be substituted for x in f(x)
• Incorrect use of the Distributive Property and subtraction leading to errors in determining the constant difference.
Questions to ask• What is different about the table of values in this activity? • What does the n-value represent?• How do you know term values, or input values, are consecutive?• Explain the meaning of the labels on the x-axis and y-axis.
Have students work with a partner or in a group to complete Questions 1 through 3. Share responses as a class.

First Differences Strategy1. Check that input values have an interval of 1.2. Subtract consecutive output values.
3. If the differences are constant, the relationship is linear.
• Have them use arrows for direction and write the subtraction for common differences.

• To assist all students, clarify the use of the terms first differences, constant differences, and common differences. First differences is a strategy to determine whether a table of values represents a linear relationship. Because constant differences and common differences have the same meaning, and common differences is primarily used for sequences, moving forward the term constant differences will be used.
MisconceptionStudents are sometimes confused as to whether the order of subtraction of table values matters. Clarify that if the x-values are in ascending order, subtracting y2 2 y1 consistently gives you first differences for comparison purposes and tells you the correct slope. Remember, slope describes both the steepness and direction of a line. If the x-values are in ascending order, subtracting y1 2 y2 consistently gives you first differences for comparison purposes, but it will not give you the correct slope. In terms of slope, the steepness value will be correct, but the direction (increasing or decreasing) will be wrong.Questions to ask
• Why does one table have an input of 0 and the other table does not?• Why is the second column titled y 5 f(x)?• Does it matter what order you subtract the values to determine if a
table represents a linear relationship? Explain.

LESSON 4: A Trip to the Moon • M2-59
Introduction to Ratio Tables
Gravity is a natural force that attracts objects to each other. Gravity is the pull toward the center of an object like the Earth, a planet, or the Moon. Your weight on the Earth is the measure of the amount of gravitational attraction exerted on you by the Earth. The Moon has a weaker gravitational force than the Earth.
The ratio of weight on Earth : weight on the Moon is approximately 60 lb : 10 lb.
You can use ratio tables to show how two quantities are related. Ratio tables are another way to organize information.
ACTIVIT Y
4.1
The table represents three equivalent ratios of weight on Earth (lb) : weight on the Moon (lb).
The ratio of 60 lb on Earth : 10 lb on the Moon is given.add
