5.OA.1. Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
5.OA.2. Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.

Anchor Standard

Write and interpret numerical expressions.

Mathematical Practice

5.OA.1
1. Make sense of problems and persevere in solving them.
7. Look for and make use of structure. 5.OA.2
1. Make sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
6. Attend to precision.

Information Technology Standard

5.TT.1 Use technology tools and skills to reinforce and extend classroom concepts and activities.

Enrichment: Explore the compexity of order of operations. Have students create and solve their own numerical expressions and defend their solutions in writing.

Give students a number and have them create complexexpressions equivalent to the number. Continually expand.
