Quick Start

Grade 7 math. 40 minutes. Topic: proportional relationships and unit rates. Illustrative sample, with general questioning and formative-assessment evidence rather than an official rubric score.

Keep the original goal: compare prices using unit rates. Upgrade the lesson with an error-analysis question, a whole-class check, and a transfer task.

Prepare: print the student handout, open the six classroom slides, and provide scrap paper. Calculators are optional. Review the answer guidance before teaching. Verify alignment to your local standards and students' access needs.

Use the same solve-explain-revise routine next week with a new context.
