• 1) The mean of the data is 9.43. I added up all the numbers (8,8,9,9,9,11,12) and divided by 7 since there are 7 pieces of data.
• 2) The median of the data is 9. I order the numbers from least to greatest and found the number in the middle.
• 3) The mode of the data is 9 because it is listed the most.
• 4) The range of the data is 4. I subtracted the smallest data from the largest data (12-8)

Dad gives you money every day to put in your new piggy bank. He gives money to you in such a way that the money in the piggy bank doubles with each passing day. If you already have 1 cent in the piggy bank and Dad gives you 1 cent the first day, 2 cents the second day, 4 cents the third day and so on, then your piggy bank gets full on the 10th day.
On which day will your piggy bank be half-full?
Day 11
If your piggy bank is full on day 10, and you are doubling your money each day, the piggy bank will
be half full on day 9.
• Day 1 1+1=2• Day 22+2=4• Day 34+4=8• Day 48+8=16 Half of 1024 = 512• Day 516+16=32 Therefore, half of the• Day 632+32=64 money would be on day
9.• Day 764+64=128• Day 8128+128=256• Day 9 256+256=512• Day 10 512+512=1024

Show all your work and/or explain your reasoning in the space provided on the answer chart.
Answer: (Explanations will vary)
• Draw a picture.
==
I began by drawing a picture of the problem. Then, I noticed that 4 circles would balance 3 triangles, since each square balances two circles. So 8 circles must balance 6 triangles.

Identify the property:
1. 7 + 0 = 72. 2 (8 + 2) = 2 (8) + 2 (2)
3. p x 3 = 3 x p4. (4 x 8) x 2 = 4 x (8 x 2)
• Answers:• 1. Identity property of addition• 2. Distributive property• 3. Commutative property of
multiplication• 4. Associative property of multiplication
Day 26
Day 30
Explain in words how to solve the following problem.
Evaluate (a – b)2 if a = 10 and b = 4
Show all your work and/or explain your reasoning in the space provided on the answer chart.
• First, substitute 10 in for a and 4 in for b.• (10 – 4)2
• Then, subtract 4 from 10 to get 6. (The order of operations says to complete parentheses before exponents.)
• Finally, square the number 6, (or multiply 6 x 6), to get 36.
Evaluate (a – b)2 if a = 10 and b = 4

Day 31Puzzler!
Old MacDonald had a farm. And on that farm he had some turkeys and pigs.
One day, while feeding them all, he noticed that , if he added everything
together, his pigs and turkeys had a total of 24 legs and 12 wings between them.
How many pigs did Old MacDonald have? How many turkeys?
• Answer:
• All 12 wings belonged to the turkeys (because pigs don’t have any); so he must have had 6 turkeys (2 wings each). The 6 turkeys have 12 legs, which leaves 12 legs for the pigs, or 3 pigs (4 legs each).
• 3 pigs and 6 turkeys
