Unit 3 · Culminating Projects
Ratios & Rates in Action
Two project versions that pull together everything from Unit 3 — writing and simplifying ratios, equivalent ratios, unit rates, and ratio tables. Pick one, or run them as differentiated options. Each is self-guided, interactive, and printable.

Two Ways to Show Mastery
🥤 Smoothie Bar Designer
Start from a real recipe in your own kitchen: write and simplify its ratio, scale it with an equivalent ratio table, and price it with a unit rate and better buy. Then compare recipes with a partner using equivalent ratios, and stack your cost per cup against real ingredient prices around the world.
Version B · Real-World Investigation🏆 Sports Stats Scout
Scout a real athlete you look up (or your own stats): compute the scoring unit rate, project a full season with a ratio table, compare with a partner's athlete using equivalent ratios scaled to the same games, and rank against real youth players around the world before writing a data-backed scouting report.

Pick Your Path
Same math, same rubric. Both versions practice the exact same skills and are graded the same way — choose the story that sounds more fun to you.
Take your time. Plan for two to three class periods. Your work saves automatically, so you can stop and come back.
Stuck on writing? Every response box has a “Need a starter?” helper, and the last step includes a Rate My Work check before you turn it in.

How to Use These Projects
Standards: 6.AT.1 (understand ratio concepts and notation), 6.AT.2 (understand unit rate), 6.AT.3 (use ratio and rate reasoning — equivalent ratios, tables, unit rates, better buy).
Both versions are parallel. They assess the same skills through different 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: live calculators with instant feedback, a progress bar, hints for scaffolding, a written deliverable, a student checklist, a 4-point rubric, and a print button so students can turn in a finished plan.
