## ◂Math Worksheets and Study Guides First Grade. Story Problems

### The resources above correspond to the standards listed below:

NE.MA.1.1. NUMBER: Students will communicate number sense concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.1.1.2. Operations: Students will demonstrate the meaning of addition and subtraction with whole numbers and compute accurately.
MA.1.1.2.a. Fluently (i.e., automatic recall based on understanding) add and subtract within 10.
MA.1.1.2.b. Add and subtract within 20, using a variety of strategies (e.g., count on to make a ten).
NE.MA.1.2. ALGEBRA: Students will communicate algebraic concepts using multiple representations to reason, solve problems, and make connections within mathematics and across disciplines.
MA.1.2.3. Applications: Students will solve real-world problems involving addition and subtraction.
MA.1.2.3.a. Solve real-world problems involving addition and subtraction within 20 in situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all parts of the addition or subtraction problem (e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem).
MA.1.2.3.b. Solve real-world problems that include addition of three whole numbers whose sum is less than or equal to 20 by using objects, drawings, and equations with a symbol to represent the unknown number in the problem.
