Exploring the Associative Property of Multiplication

What is the essential question of this lesson?

• How can we use the commutative property of multiplication?

• How can we use the associative property of multiplication to find products?

• How can we use the distributive property of multiplication?

• What is the difference between addition and multiplication?

What must you do first when you see parentheses in an addition problem?

• Add the numbers outside the parentheses first

• Multiply the numbers inside the parentheses

• Add the numbers inside the parentheses first

• Subtract the numbers inside the parentheses

What does the associative property of multiplication allow you to do?

• Change the order of the numbers being multiplied

• Regroup the factors to multiply different numbers first

• Add the numbers before multiplying

• Subtract the numbers before multiplying

In the roller coaster example, how many seats are there in each car?

• 6

• 2

• 8

• 4

What is the product of 3 times 4 in the roller coaster example?

• 8

• 10

• 12

• 14

What does the commutative property of multiplication allow you to do?

• Regroup the factors

• Subtract the factors

• Change the order of the factors

• Add the factors

In the example 6 times 3 times 2, what is the result of associating 3 times 2 first?

• 36

• 12

• 6

• 18

What is the product of 6 times 25 times 4 when using the associative property to group 25 and 4 first?

• 100

• 1000

• 600

• 150

What is the product of 2 times 5 times 7 when using the associative property to group 2 and 5 first?

• 70

• 50

• 35

• 10

Why is it sometimes easier to use the associative or commutative property in multiplication?

• It changes the final product

• It makes the numbers smaller

• It allows you to add the numbers first

• It helps to target easier numbers to multiply first
