Multiplication & Division Properties

Standard(s): 3.OA.B.5

Use the Distributive Property to rewrite the following expression:

9 x 22

A

(9 x 20) + (2 x 2)

B

(9 x 20) + (9 x 2)

C

(9 x 20) + 2

D

2 x (20 + 9)

## Standard: 3.OA.B.5

## Domain: Operations & Algebraic Thinking

## Theme: Understand properties of multiplication and the relationship between multiplication and division

## Description: Apply properties of operations as strategies to multiply and divide. Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15 then 15 × 2 = 30, or by 5 × 2 = 10 then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.) (Students need not use formal terms for these properties.)

Use the Distributive Property to rewrite the following expression:

25 x 9

A

(20 x 5) + (9 x 5)

B

(20 x 9) + (5 x 9)

C

(9 x 20) + (5 x 20)

D

9 x 20 x 5

Use the Distributive Property to rewrite the following expression:

8 x 19

A

(8 x 10) + (9 x 10)

B

(8 x 20) - (19 x 8)

C

(8 x 20) - (8 x 1)

D

(19 x 8) x 1
