Perfect Squares and Cubes Concepts

This lesson covers the concepts of perfect squares and perfect cubes, explaining how to identify them and use exponents to express areas and volumes. Students engage in a hands-on activity using snap cubes to build and understand cubes. The lesson concludes with a summary of key concepts and a challenge to find numbers that are both perfect squares and cubes.
