3.OA.A.3

Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

3.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.*

Solve division problems by relating to multiplication. For example, find 16 / 2 by finding the number that makes 16 when multiplied by 2. Start with arrays and equal groups, then move away from them. Then relate multiplication to division via word problems. *For example, 5 * 7 = 35 and 7 * 5 = 35 are related to 35 / 7 = 5 and 35 / 5 = 7.*
