MAT-03.OA.03

MAT-03 Targeted Standards
(OA) Domain: Operations and Algebraic Thinking
Cluster: Represent and solve problems involving multiplication and division.

MAT-03.OA.03 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.
