MAT02 Targeted Standards (OA) Domain: Operations and Algebraic Thinking Cluster: Represent and solve problems involving addition and subtraction.
MAT02.OA.01 Use addition and subtraction within 100 to solve one and twostep word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
