Design a Dream Bedroom – Area & Perimeter Project

About this resource

What's inside this resource

A multi-day performance task has students design and budget a bedroom remodel from start to finish. After drawing a birds-eye blueprint labeled with wall dimensions and calculating the room's area in square feet, students choose from priced catalogs of furniture, flooring, wall paint, custom textiles, and decorative accessories, calculating the cost of each category using real per-item and per-square-foot pricing. A summary page has students total every component into one final cost and reflect on the design process, before writing a letter to their parents explaining and justifying every choice they made. A teacher scoring rubric is included for assessing student work, along with teacher notes on typical project length, materials setup, and classroom implementation.

Product description

From the author

Bring math lessons to life with this engaging real-world project where students design their dream bedroom! Students step into the role of an interior designer, using math skills to draft blueprints, select flooring and paint, purchase textiles and accessories, and calculate costs. The multi-part open-ended performance tasks integrate geometry, perimeter, area, multiplication, number operations, and conventions over 16 pages. Differentiation allows all learners to be successful while gifted students can dive deeper. Use for individuals, partners, or small groups as an assessment, enrichment, end-of-year project, or gifted curriculum. This creative endeavor taps into students’ interests, bringing out perseverance as they beg for more time. Easily implement as-is or alongside physical samples.

Teaching tips & learning objectives

Learning objectives

Students can calculate the area of a rectangular room in square feet from a labeled blueprint.
Students can calculate total cost across multiple pricing categories, including cost-per-square-foot flooring and per-unit furniture and accessories.
Students can create an accurate labeled blueprint (birds-eye view) showing room dimensions and furniture placement.

Teaching tips

Plan for 5 days to 2 weeks of work time, since the teacher notes describe this as a multi-day project rather than a single-sitting worksheet.
Allow calculators during the project, as the teacher notes explain that the complexity of the thinking is the point, not computational fluency.
Use the included scoring rubric to assess student thinking the way you would assess a writing sample, per the teacher notes' own suggested approach.

Skills covered

Area calculation — measuring a rectangular room's square footage from a hand-drawn, dimensioned blueprint.
Multi-step cost computation — multiplying per-square-foot flooring prices and summing per-item furniture, textile, and accessory costs into category and grand totals.
Scale/blueprint drawing — creating a labeled birds-eye-view floor plan with furniture placed within a maximum 30' x 35' footprint.

Good to know

Questions teachers ask about this resource

How open-ended is the final design and budget?

Entirely open-ended — students choose their own furniture, flooring, paint, textiles, and accessories from priced lists, so the totals and final design differ for every student.

What is the maximum room size students can design?

Wall dimensions cannot exceed 30 feet by 35 feet, per the blueprint guidelines.

Curriculum

Standards, concepts & topics

Standards

4.MD.A.3 — Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
4.MD.A.2 — Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.
