Unit 4 · Culminating Projects
Percents & Rates in the Real World
Two project versions that pull together everything from Unit 4 — unit rates, unit price comparisons, percent of a number, percent discounts, sales tax, and measurement unit conversions using rate reasoning. Pick one, or run them as differentiated options. Each is self-guided, interactive, and printable.

Two Ways to Show Mastery
🛍️ Pop-Up Shop Owner
Launch your own pop-up shop with real products: set prices with 10%, 20%, and 25% discount options, compare bundle deals by unit rate, and add sales tax. Then compare shops with a partner and test your price against real U.S. state sales-tax rates (Self → Peer → World).
Version B · Real-World Investigation🛒 Smart Shopper Showdown
Become the savviest shopper around: compare real packages by unit price to find the better buy, calculate percent savings on a sale, and add up a grocery bill with sales tax. Then compare buys with a partner and test your spending against real weekly grocery budgets (Self → Peer → World).
For the Teacher
How to Use These Projects
Standards: 6.RP.2 (unit rates), 6.RP.3b (unit price / better buy), 6.RP.3c (percent of a number, discounts, tax, fraction-decimal-percent conversions), 6.RP.3d (measurement unit conversion using rate reasoning — featured in Version A's Level 2 challenge).
Both versions are parallel. They assess the same rate and percent skills through different real-world contexts, so you can assign Version A and Version B to different students and grade on the same rubric (built into each project). Great for choice boards, make-up work, or A/B class sections.
Built in: a Self → Peer → World arc, Visual Math Notes vocabulary, a Formula Bank and Sentence Frames, an EN/ES toggle, Level 1 / Level 2 differentiation, live calculators with self-checks, peer-compare and world-data tools, save/resume and a report export (.txt), a sticky progress bar, hints, a written deliverable, a student checklist, a rubric, and a print button.
