# Lesson 14

Wax Prints

### Lesson Purpose

The purpose of this lesson is for students to consider how geometric attributes, perimeter, and area are used to design and use wax print fabric.

### Lesson Narrative

In previous lessons, students learned how to identify different types of quadrilaterals and solve problems involving area and perimeter. In this lesson students put all of their learning together to analyze geometric attributes of wax prints, then design a wax print of their own with specific constraints about the shapes they need to use. Then, students use what they know about area and perimeter to solve problems that involve wax print fabric.
