Math Module: First Grade

This first grade math module (in draft form) covers adding and subtracting single-digit numbers and addresses the following standards.

1. Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (1.OA.1)

2. Relate counting to addition and subtraction (e.g., by counting on 2 to add 2). (1.OA.5)
