Math Module: First Grade

Standards Addressed by this Resource

1.OA.5 : Relate counting to addition and subtraction (e.g., by counting on 2 to add 2). 1.OA.6 : Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

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

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