# Lesson 4

Minicasa: Diseñemos y resolvamos

### Lesson Purpose

The purpose of this lesson is for students to design and solve problems about a tiny house.

### Lesson Narrative

In an earlier unit, students learned about area and perimeter. In this lesson, they apply their understanding of area and perimeter and their creativity to design a tiny house, which is generally a house under 400 square feet. After students design their tiny house (along with the furniture and other details), they write, revise, and answer problems involving area and perimeter that can be answered using their design.

If students need additional support with the concepts in this lesson, refer back to Unit 2, Section B in the curriculum materials.
