Lesson 7

Different Square Units (Part 2)

Lesson Purpose

The purpose of this lesson is for students to learn about square feet and square meters, and consider when these larger units can be helpful to measure area.

Lesson Narrative

In a previous lesson, students learned about the difference between square inches and square centimeters. In this lesson, students work with square feet and square meters, building on their work with feet and meters in grade 2. Students consider different areas in real-world situations and choose a square unit that would be the most useful to measure each given area.
