Give an example of the Distributive Property. Explain why is can also be called the Break Apart Property.
8x7 = 7 x (4+4) = (7x4) + (7x4) = 28+28 = 56
You break apart of problem into two smaller problems and combine their answers.

Give an example of each Property:
Commutative Property of Multiplication
Associative Property of Multiplication
How are they alike and different?
CP: 3x4 = 4x3 OR (3x4) x 2 = (4x3) x 2
AP: (3X4) x 2 = 3 x (4x2)
Alike: Both rearrange the numbers
Different: CP flip flops the order of the same numbers; AP groups different numbers together.

1. What is repeated in these equations? Use what you see to make a generalization.
6 × 6 = (6 × 3) + (6 × 3) = 18 + 18 = 36
7 × 6 = (7 × 3) + (7 × 3) = 21 + 21 = 42
8 × 6 = (8 × 3) + (8 × 3) = 24 + 24 = 48

11.Amy arranged her counters into this array.
A. What two facts could Amy use to write an equation for the array?
B. If Amy adds one more row of 9 counters to her array, can she still use the facts you wrote in Part A to find the total number? Explain why or why not.
A: 1x9 and 2x9 (example)
B: No, Amy would now have a 4x9 array. 1+2 = 3, not 4.

Define the following terms:
factor, product, multiple
Explain the similarities and difference in products and multiples.
factor: the numbers being multiplied together in a multiplication equation (ex: 3x5 = 15, 3 and 5 are the factors)
product: answer to a multiplication equation
multiple: product of a specific number and each counting number
Products and multiples are both answers to multiplications equations. A product is an answer. A multiple is a specific answer.
