Instructional Outcomes
2.OA.A.1: 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.
