No Prep Sub Plans: Area & Perimeter: Measuring Space Research + STEM Project |Design a Floor Plan Grades 5–8

Bring geometry to life with this engaging, real-world math and STEM design challenge!

In this collaborative middle school activity, students explore area and perimeter by designing a realistic floor plan for a small building or home. Students research formulas, analyze room dimensions, sketch layouts, calculate measurements, and solve practical design problems while applying geometry to architecture and construction.

This lesson combines math, STEM, problem solving, creativity, and collaboration into a highly engaging project that is easy for a substitute teacher to facilitate in a single 45–50 minute class period.
Perfect for Math, STEM, Geometry, architecture-themed projects, or cross-curricular learning!
