Grade Level/ Course: 5th Grade Standard with code: Domain: 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 x (8+7). Recognize that 3 x (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum of product. Operations and Algebraic Thinking Cluster: Write and interpret numerical expressions.
