Standard 5.OA.2 Write and interpret simple numerical expressions. a. Write simple expressions that record calculations with numbers. For example, use 2 x (8+7) to express the calculation "add 8 and 7, then multiply by 2 ." b. Interpret numerical expressions without evaluating them. For example, use conceptual understanding of multiplication to interpret 3 x (18939 + 921) as being three times as large as18932 + 921 without calculating the indicated sum or product.
