## Algebra - Expressions

**I can write expressions I hear using mathematic symbols and the order of operations. 5.OA.2**

*5th graders are expected to 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.*
