Product description
Percent Change & Percent Error: Real-World Discovery Unit for 7th Grade Math | CCSS 7.RP.A.3
Help your 7th graders understand percent change and percent error through discovery, real-world data, and hands-on investigation. This 44-page unit has students build the formulas using stock prices, sports statistics, and a measurement lab before applying their understanding through three real-world practice stations.
★ WHAT MAKES THIS UNIT DIFFERENT ★
• **Discovery-Based Learning** — Students derive percent-change and percent-error formulas from real data and hands-on measurement rather than simply memorizing formulas.
• **2 Full Lesson Scripts** — 25-minute lessons with anticipated student responses, teacher moves, and guided discovery moments.
• **3 Station Rotation Cards** — 8 problems per station, for 24 total problems:
* Retail — Markups & Markdowns * Science & Weather — Percent Error * Financial Literacy — Multi-Step Applications
• **Hands-On Measurement Lab** — Students measure the same object with a ruler and tape measure, record their results, and use the data to explore percent error.
• **Labeled Visuals** — Includes a percent-change number-line model and a percent-error formula breakdown.
• **Fill-in-the-Blank Student Notes** — Students record and build the formulas themselves.
• **Complete Answer Keys** — Step-by-step solutions for all 24 station problems, the exit ticket, and the 10-question quiz with scoring rubric.
