**In This Unit of Study…**

Students will use addition within 20 and related subtraction facts to solve real-world problems involving situations of adding to, taking from, putting together, taking from, and comparing. In order to solve real-world problems, they will understand the context while representing problems by using objects, drawings, and equations. Students are not expected to independently read word problems.

**B.E.S.T. Benchmarks:**

- MA.1.NSO.2.2 Add two whole numbers with sums from 0 to 20 and subtract using related facts with procedural reliability.
- MA.1.AR.1.2 Solve addition and subtraction real-world problems using objects, drawings, or equations to represent the problem.

**Key Concepts:**

- I can add two whole numbers with sums from 0 to 20.
- I can subtract two whole numbers using related addition facts.
- I can solve real-world problems using addition and subtraction within 20 involving situations of adding to, taking from, putting together, taking apart, and comparing with unknowns in all positions by using objects.
