Unit 10 · Culminating Projects
Volume & Surface Area in Action
Two project versions that pull together everything from Unit 10 — volume of rectangular prisms with whole and fractional edge lengths, surface area from nets, and real-world cost decisions. Pick one, or run them as differentiated options. Each is self-guided, interactive, and printable.

Two Ways to Show Mastery
📦 Package Design Challenge
Be a packaging engineer: compute the volume of a shipping box, work with fractional edge lengths to count unit cubes, unfold the net to find surface area, and calculate the cardboard material cost.
Version B · Real-World Investigation🐠 Aquarium Build Lab
Design a custom fish tank: find the full volume, calculate how much water fills it at a set height, compute the glass needed for an open-top tank (5 faces — no lid!), and determine the total glass cost.
For the Teacher
How to Use These Projects
Standards: 6.G.2 (volume of rectangular prisms with whole-number and fractional edge lengths) and 6.G.4 (surface area using nets, including rectangular prisms).
Both versions are parallel. They assess the same 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. Version B adds the important distinction between a closed-box surface area and an open-top tank (5 faces vs. 6 faces), making it slightly more challenging.
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.
