Winter Progress Monitoring and Instructional Strategies for 3.OA.5
Winter Progress Monitoring and Instructional Strategies for 3.OA.5
Standard:
Apply properties of operations as strategies to multiply and divide. Examples: if 6 x 4 = 24 is known, then 4 x 6 = 24 is also known. (Commutatve property of multiplication.) 3 x 5 x 2 can be found by 3 x 5 = 15, then 15 x 2 = 30, or by 5 x 2 = 10, then 3 x 10 = 30. (Associative property of multiplication.) Knowing that 8 x 5 = 40 and 8 x 2 = 16, one can find 8 x 7 as 8 x (5 + 2) = (8 x 5) + (8 x 2) = 40 + 16 = 56. (Distributive property).
