Mathematics | Grade : 5
Domain - Operations and Algebraic Thinking
Cluster - Write and interpret numerical expressions.
[5.OA.A.1] - Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols, e.g.,(6 x 30) + (6 x 1/2).
- Expression
A mathematical phrase that combines operations, numbers, and/or variables (e.g., 32 ÷ a).
[5.OA.A.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 or product.
