Look at problem A. What multiplication sentence can you write to represent the array shown?
3 x 4 = ? or 4 x 3 = ?
What is a related division sentence for the multiplication sentence?
Why is it possible to use both 3 x 4 = ? and 4 x 3 = ? for the array?
It doesn't matter what number you multiply first because the product stays the same.
What does each number stand for in the equation?
3 groups of 4, or 4 groups of 3.
Look at problem B. What division sentence represents the problem?
What is a related multiplication sentence for the division sentence?
5 x ? = 35 or ? x 5 = 35
What does the quotient represent in the equation?
The number of cupcakes on each tray.
Use repeated subtraction to solve
The quotient is 7.
Look at problem C. How can you find the product? Explain your answer.
Possible responses: Multiply 5 x 4 to get 20 and then multiply 20 x 2 to get 40. Multiply 5 x 2 to get 10 and then multiply 10 x 4 to get 40. Multiply 4 x 2 to get 8 and then multiply 8 x 5 to get 40. It doesn't matter what order you multiply the numbers in, because the product stays the same.
Look at problem D. Why are the 2 multiplication problems equal?
8 is decomposed to 5 + 3, and the parentheses show that you add 5 + 3 first to get 8.
