Number Properties

Which property is shown?

• 4(3x4)=4 x 12

• 4x3=3x4

• 4+3=3+4

• 12 x 4 = 4 x 12

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)

Does order matter when multiplying numbers?

• Yes

• No

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)

3 x 5 = 5 x 3 is an example of which property?

• Associative

• Distributive

• Commutative

The commutative property of multiplication says "The order of factors in a multiplication problem...."

• should always be from least to greatest

• Should always be from greatest to least

• won't change the product

• can never be changed

Rewrite 9 x (6 x 5) using the associative property:

• 270

• (9 x 6) x 5

• 9 x 6 + 6 x 5

• 965

Which property tells us that 6 x 4 = 24 AND 4 x 6 = 24?

• Associative Property

• Commutative Property

• Distributive Property

According to the distributive property, another way to solve 12 x 6 is...

• (10 x 6) + (2 x 6)

• 12 + 12 + 12 + 12 +12 +12

• 12 + 6

Which equation shows the associative property?

• 3 x (2 x 7) = (3 x 2) x 7

• 5 x 0 = 0

• 18 x 4 = (10 x 4) + (8 x 4)

• 3 x 7 = 7 + 7 + 7
