Baseboard Trim Estimation: Perimeter
Trim It Right is a real-world geometry worksheet where students take on the role of a construction estimator. Using a detailed floor plan plotted on a coordinate grid, students measure the dimensions of each room and calculate the perimeter using the formula 2 × (Length + Width). As they input correct values, visual feedback in the form of green check marks reinforces learning.
Once all perimeters are calculated, students find the total trim needed and estimate the cost of materials based on a given rate per foot. This activity helps students connect perimeter calculations to real-life applications in construction, interior design, and home improvement.
🔍 Key Features:
- Coordinate grid-based floor plan
- Focus on perimeter of rectangles
- Real-world scenario: estimating trim needed
- Includes cost calculation for added relevance
- Instant visual feedback with auto-validation
- Great for exploring math-in-the-real-world
Perfect for making geometry meaningful, this worksheet reinforces core skills while engaging students with a task that mirrors real-life decision-making.
Learning Objective
Students will apply their understanding of perimeter by measuring dimensions of rectangular rooms on a coordinate grid-based floor plan and calculating the perimeter of each room using the formula 2 × (Length + Width). They will then determine the total baseboard trim required for the apartment and calculate the associated cost, reinforcing the real-world application of geometry in construction and budgeting.
