Unit 5 · Culminating Projects
Area in Action
Two project versions that pull together everything from Unit 5 — parallelogram area, triangle area, trapezoid area, and composite figures. Pick one, or run them as differentiated options. Each is self-guided, interactive, and printable.

Two Ways to Show Mastery
🏠 Dream Room Designer
Measure your own real bedroom and calculate its area: a rectangular main floor (length × width) plus a triangular reading nook (½ × base × height). The total area auto-sums and prices your flooring. Then compare your room size and cost with a partner.
Version B · Real-World Investigation🎨 Room Makeover Budget
Plan a room makeover: calculate the floor area (length × width), then the wall paint coverage — gross wall area 2 × (L + W) × height, minus window and door openings — and round up to whole gallons of paint. Price out flooring and paint for a total makeover budget, then compare your plan with a partner.

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.GR.1 — Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes. Version B also touches 6.GR.4 (represent 3-D figures using nets and find surface area) through its wall paint-coverage work. Apply these techniques in the context of solving real-world and mathematical problems.
Both versions are parallel. Both start from a rectangular floor area and apply area/coverage skills in a different real-world context, so you can assign Version A and Version B to different students and grade on the same style of rubric (built into each project). Great for choice boards, make-up work, or A/B class sections.
Built in: Visual Math Notes vocab, live calculators with instant feedback, an EN/ES toggle, Read-Aloud, Level 1 / Level 2 tiers, and Save/Resume. Students measure real spaces, the total area auto-sums to feed the cost phase, they compare their results with a partner and against real-world price ranges, and a progress bar, SVG sketches, hints, a written deliverable, a checklist, a rubric, report/export (.txt), and a print button round it out.
Key formulas covered: Rectangle / parallelogram — length × width (b × h); Triangle — ½ × b × h; Wall surface coverage — 2 × (L + W) × height, minus window and door openings. Version B also introduces ceiling rounding (Math.ceil) for whole gallons of paint (1 gallon ≈ 350 sq ft) as a real-world application of why you "round up" in some contexts.
