Writing and Solving Numerical Expressions with Parentheses
A 5th-grade practice set of about 10 to 15 problems where students translate word phrases such as "50 times the sum of 64 and 36" into numerical expressions using parentheses, then solve them. It builds order of operations fluency and the skill of reading mathematical language accurately, and it is well suited to a 30-minute independent practice block or a guided partner activity.
Teacher Guide & Tips
- Use this as a guided "I do, we do, you do" lesson: model one phrase aloud with parentheses, work one together, then let students finish the rest on their own.
- Discussion question: Why do the parentheses matter in "divide the difference between 1,200 and 700 by 5" compared to writing it without them?
- Scaffold for struggling readers: Have them underline the operation words (sum, difference, times, divide) and box the numbers before writing any symbols.
- Extension for advanced students: Ask them to write their own word phrase for a given expression, such as (3 × 15) + (17 × 15), and trade with a partner to solve.
- Estimated time: about 20 to 30 minutes for the full set, plus a few minutes to review the answer key together.
