Description

This is a 12 day unit to teach 3rd Grade Common Core Math Standards 3.OA.5, 6 and 7-Different strategies for Multiplication. Students will write multiplication sentences for arrays using the commutative property, decompose a one and two digit factor to solve a multiplication problem (distributive property), solve multiplication problems with 3 one-digit factors using the associative property, solve division problems by finding the unknown factor in a multiplication problem, write fact families for a division or multiplication problem, learn doubles multiplication facts, learn the double, double strategy, the double, double, double strategy, 10's multiplication facts, the half of 10 (5's) strategy and finally, skip counting on a number line and solving 9's by 10 groups less one group strategy. This unit has everything you need to teach these standards. This unit includes:

CCSS3.OA.B.5

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.)

CCSS3.OA.B.6

Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8.

CCSS3.OA.C.7

Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
