Collaborative: The Classroom Makeover Project
This approach puts students into design teams with shared roles to plan and cost a real space. Working together on one deliverable builds communication and lets students check and challenge each other’s measurements.
The brief: “Your team has a budget to refresh a corner of the classroom (or a garden bed outside). Measure it, design it, and cost it. The team with the most accurate, best-value plan wins the tender.”
Assign roles. Surveyor (takes and records measurements), Designer (sketches the plan to scale), Accountant (works out areas, volumes and costs), and Presenter (prepares the pitch). Rotate roles between tasks so everyone measures and calculates.
Measure and plan. Teams measure the real space, convert units as needed, and calculate perimeter, area and any volumes (e.g. soil or paint).
Cost it. Using a shared price list (fencing per metre, paving per m², soil per bag), teams total their plan and check it against the budget, then look for a saving.
Cross-check. Teams swap plans and audit each other’s arithmetic and unit conversions before the final pitch.
Why it works. A shared, authentic deliverable makes measurement choices matter, and the audit step turns checking and justifying into a natural part of the teamwork.
