Lesson 5
Tiny House: Cost
Lesson Purpose
The purpose of this lesson is for students to apply what they’ve learned about operations to calculate the cost to finish a space in a tiny house.
Lesson Narrative
In a previous lesson, students used what they learned about area and perimeter to design a tiny house. In this lesson, they apply their knowledge of operations to calculate the cost of finishing one of the rooms of their tiny house. Students engage in aspects of mathematical modeling as they make decisions about quantities, relate measurements and costs, and interpret their results in context (MP4).
If students need additional support with the concepts in this lesson, refer back to Unit 3, Section A in the curriculum materials.
