Discount Challenge: Sale Prices for 7th Grade
A self-checking, room-based Google Form practice set in which 7th graders find sale prices after percent and fraction discounts, using their answers to unlock each section's lock code. It builds proportional reasoning (7.RP.3) through three themed rooms of three questions each, with a worked example to support first attempts.
“Create a self-checking Google Form where students must enter the correct answers to unlock the next "room" or section. Structure Example: Room 1 (The Outlet Mall): 3 questions on finding sale prices after discounts. Room 2 (The Food Truck): 3 questions on calculating tax and tips on meal totals. Room 3 (The Architect's Studio): 3 questions using scale drawings to find actual room sizes.”
Teacher Guide & Tips
- Use this as a 30-45 minute independent or partner station after you've modeled percent-off problems, so students arrive already familiar with turning percents into decimals.
- Discussion question: Why does multiplying the original price by 0.25 give the amount saved, and how could you check that your sale price is reasonable without a calculator?
- Scaffold for struggling readers: Have them work through the worked example aloud, then complete Room 1 with the step-by-step method card visible before moving on to the harder rooms.
- Extension for advanced students: Ask them to compare two discounts (for example, 30% off versus 1/3 off) and explain which offers the better price, or to find the discount rate that produces a given sale price.
- Estimated time: Roughly 5 minutes per room, plus a few minutes of discussion at the end to review any digits students found tricky.
