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.2.1 Recall addition facts with sums to 10 and related subtraction facts with automaticity. 
• MA.1.AR.1.2 Solve addition and subtraction real-world problems using objects, drawings, or equations to represent the problem. 
• MA.1.AR.2.3 Determine the unknown whole number in an addition or subtraction equation, relating 3 whole numbers, with the unknown in any position. 

Key Concepts:

• Fluency: Make a ten to recall addition facts within 10
• Solve add to/take from real world problems with the unknown in all posistions.
• Solve put together real world problems with the unknown in all positions.
