Exploring Perimeter and Area Project-Based Learning Unit

Students Design a Floorplan for a Tiny House Using Area and Perimeter

Learn about tiny houses, think like an architect to design the perfect floor plan, use measurement and conversion skills to design furniture to scale, use formulas to compute area and perimeter, and synthesize that knowledge by designing and creating a professional floor plan for a tiny house!

Your students will think like architects and builders in this project-based learning unit for grades 5-7 math. They'll learn all about tiny houses, use measurement and conversion formulas to compute area and perimeter, plan and problem-solve for tricky layout and building issues, and then design and create a professional floor plan for a tiny house, including scaled furniture.

What's Inside

Packed with hands-on inquiry-based activities, extensions and enhancements, cross-curricular independent and group work, and engaging and interactive challenges, this 48-page project-based unit comes complete with:

  • For the Teacher: A complete Perimeter and Area Lesson Plan with step-by-step instructions for all activities, teaching tips, assessment guidance, and inquiry questions.
  • For Students: A full-color Student Pack complete with all of the printables, slides, photos, and instructions students need for the research, experiments and activities - just print (or share) and teach!

A complete, ready-to-teach Teacher Pack that includes:

  1. Teacher versions of all the student printables with step-by-step annotations and notes for teaching perimeter and area, scale measurements, and floorplan layout;
  2. Formative and summative assessments, answer keys, and a full project rubric;
  3. Instructions and guidance for the extension activities and project enhancements;
  4. Materials and resources lists, links to articles, videos, and research, plus additional resources for lecture and presentation.

Student Pack - Exploring Perimeter and Area Project-Based Learning Lesson


This project-based learning lesson is designed to support and reinforce the concepts taught as part of a math lesson or unit on perimeter and area, measurement and conversion, and scale. It is built around 5 inquiry-based milestones that incorporate cross-curricular hands-on projects, formative and summative assessments, independent and group activities, and extensions.


In the course of this project-based learning unit, students will:

  • Build background knowledge about tiny houses by researching and studying them in detail;
  • Explore the house design and building process by learning about floor plans and modeling measurements to scale;
  • Use specific formulas to compute area and perimeter for their house designs;
  • Learn how to apply measurement and conversion skills to design properly-scaled furnishings;
  • "Show what they know" by designing and creating a professional floorplan for a tiny house and scale furniture.


Students will acquire necessary background knowledge of area and perimeter and measurement and conversion as part of this project, and instructional materials for providing that background are included in the Teacher Pack. 


This project-based unit is divided into 5 milestones. The minimum suggested duration for completing this project-based unit is 5 class periods. However, the unit is completely flexible can be lengthened or shortened as necessary or desired, based on available class time and interest level.
