Lesson Title Math Skills for Carpet & Tile Installation
Unit Title Construction & Trades
NRS Level Level 3; Level 4; 
Length of Lesson 60 minutes
Lesson Purpose

This lesson shows students how math skills can be applied to make improvements to their own living spaces. It also shows them how they would use these math skills if they were employed in the trade jobs of carpet laying or tile setting. This lesson builds on the unit’s aim to help students explore trade jobs.

Lesson Objectives

At the end of this lesson, students will be able to calculate square footage and the amount of materials needed for an installation and calculate the cost including taxes. Students will watch the instructor make calculations for a carpet or tile installation for the classroom. Students will then work in groups of three to make calculations for carpet and tile installation from a given blueprint, and, finally, students will work independently to make calculations for carpet installation in a different room somewhere in the building.


Student Target

“I can calculate square footage, the amount of materials needed for an installation, and calculate the cost including taxes.”


CCR Focus Standards
Geometry - Level C
Number and Ratios - Level D
Supporting Standards
  • 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.

  • Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

  • Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real world problems.

Standards for Mathematical Practice
  • Make sense of problems and persevere in solving them. (MP.1)

  • Model with mathematics. (MP.4)

  • Use appropriate tools strategically. (MP.5)

KYAE Employability Standards
  • E.1 Effectively contribute to a team through cooperation, leadership, and giving and accepting critical feedback to work toward a common goal.

  • E.6 Identify and effectively use skills and materials needed for a particular task.

  • E.7 Accurately analyze information and respond appropriately.
