Multiplication And 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

B
12 x 7 = 7 x 12
C
12 x 4 = 48
