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.

How to Use These Projects
Standards: 6.G.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.G.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.
