Equivalent Expressions and Problem Context for Grade 7
A practice set of about 2 to 3 pages that helps 7th graders see how different algebraic expressions can describe the same real-world situation, such as a 20% discount written as j − 0.20j or 0.80j. It builds skills aligned to CCSS 7.EE.A.1 and 7.EE.A.2 through worked examples, tape diagrams, and context-based problems, and it is well suited to a 45-minute lesson or independent practice.
“practice problems”
Teacher Guide & Tips
- Use this as a guided practice block after a short mini-lesson on the distributive property and equivalent forms, ideally in a 45-minute period with pairs working through the worked example first.
- Discussion question: Why might a shopper prefer to see the sale price as 80% of the original rather than as the original minus 20%? Ask students to explain which form makes the discount or the final cost easier to see.
- Scaffold for struggling readers: have them draw the tape diagram for the jacket example first, labeling the whole as j and shading the discount and the remaining part before writing any expression.
- Extension for advanced students: ask them to write three equivalent expressions for a 35% markup and justify which one best fits a store manager's budgeting goal.
- Estimated time: about 20 to 25 minutes for the worked example and first problems, with the remaining practice taking another 15 to 20 minutes.
