Properties of Multiplication

The commutative property says that if 4x6=24, then

• 3x8=24

• 4x5=20

• 6x4=24

• 6+4=10

Which two problems show the identity property?

• 6x1=7

• 19+1=20

• 37x1=37

• 64x1=64

Use the commutative property of multiplication to solve the equation.
5 x 2 = 10, so ____ x 5 = 10

• 10

• 5

• 2

• 7

Mr. Weir wants to multiply 5 x 6 x 8. Which equation shows a way he can find the product?

• 5 x 1 = 6 x 1 = 8 x 1

• 5 x 6 = 6 x 8

• 3 x 4 x 2 + 7 = 31

• (5 x 6) x 8 = 5 x (6 x 8)

Use the associative property to write 9 x 2 x 3.

• (9 x 2) x 3 = 9 x (2 x 3)

• 9 x 2 = 9 x 3

• 9 x 2 = 2 x 9

• 9 x 2 = (9 x 2 x 3)

Which equation correctly shows the total number of Pokemon cards Carson lined up?

• 3 x 6 = (3 x 2) + (3 x 4)

• 3 x 6 = ( 3 x 2) + (3 x 2)

• 3 x 6 = (3 + 2) x (3 + 4)

• 3 x 6 = (3 + 2) + (3 + 4)

Megan has 64 pieces of Halloween candy to share equally in a party favor bag for each of her 8 guests at the party. Which multiplication equation could Megan use to show how many pieces of candy each guest received in their bag.

• 64 x 8 = 8

• 8 x 8 = 64

• 8 + 8 = 16

• 64 x 8 = 8

Amy is trying to multiply a strand of numbers (5 x 4 x 2) in her head but is having trouble keeping them organized in her head. Which property can help her to find the answer?

• Distributive Property

• Associative Property

• Commutative Property

If one box of cupcakes costs 4 dollars, how much would 6 boxes of cupcakes cost?

• 10

• 28

• 36

• 24

What is another way to group the factors

(2 x 3) x 6

(Think Associative Property)

• (6 x 2) x3

• 6 x (2 x 3)

• 2 x (3 x 6)

• 6 x (2 x 3)
