Algebraic Expressions and Rational Numbers Review
By Mr. C. G.
A two-part review sheet (multiple choice plus open-response) for 7th graders covering simplifying algebraic expressions, perimeter of polygons with variable side lengths, and operations with rational numbers. It is built as a Version A test-prep sheet that pairs with a second version for the same unit test, and it works well as a quick study guide before a unit exam.
Customize for your classroom
Teacher Guide & Tips
- Use as a 30-45 minute review station or homework the night before the test, with students working individually before checking answers as a class.
- Discussion question: Why can we only combine terms like 9x and x, but not 9x and 2y, when simplifying an expression?
- Scaffold for struggling readers: Have them rewrite each expression with like terms grouped by color or underline before combining, and model one problem aloud step by step.
- Extension for advanced students: Ask them to write their own perimeter problem with variable side lengths and a rational-number coefficient, then trade with a partner to solve.
- Estimated time: about 35 minutes for the full sheet, plus 10 minutes for review of missed items.
