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
Design your dream bedroom floor plan: calculate the main floor area using the parallelogram formula, measure a triangular reading nook with the triangle formula, map out a composite L-shaped bonus room, and price the flooring.
Version B · Real-World Investigation🎨 Community Mural & Garden Planner
Plan a school community garden and gym mural: calculate the trapezoid-shaped garden plot, find paint coverage for a triangular mural panel (with ceiling rounding), measure a parallelogram banner, and decide which plot fits the $600 budget.

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. Apply these techniques in the context of solving real-world and mathematical problems.
Both versions are parallel. They assess the same area formulas 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: live calculators with instant feedback, a progress bar, inline SVG shape sketches, 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.
Key formulas covered: Parallelogram — b × h; Triangle — ½ × b × h; Trapezoid — ½ × (b1 + b2) × h; Composite — sum of decomposed parts. Version B also introduces ceiling rounding (Math.ceil) for paint cans as a real-world application of why you "round up" in some contexts.
