Third graders will solve addition and subtraction problems with procedural fluency. This includes word problems, multistep problems, and problems that require regrouping.

B.E.S.T. Benchmarks:

• MA.3.NSO.2.1  Add and subtract multi-digit whole numbers including using a standard algorithm with procedural fluency.
• MA.3.AR.1.2  Solve one- and two-step real-world problems involving any of four operations with whole numbers.

Overarching Key Concepts:

• Add within 10,000 by making connections between place value strategies and a standard algorithm
• Subtract within 10,000 by making connections between place value strategies and a standard algorithm
