#### MAT-03.OA.03

 MAT-03 Targeted Standards (OA) Domain: Operations and Algebraic ThinkingCluster: 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.

## Student Learning Targets:

### Reasoning Targets

• I can understand the relationship between multiplication and division.

### Skills (Performance) Targets

• I can use multiplication and division within 100 to solve word problems.
• I can represent the problems using pictures of equal groups, arrays, and equations.
