Understanding Nets of Three-Dimensional Figures

In this lesson, Mr. Hul introduces the concept of nets, which are two-dimensional representations of three-dimensional figures. The lesson focuses on how nets can be used to visualize and construct 3D shapes, specifically cubes. Through a series of exercises, students learn to identify which patterns can be folded into a cube. The lesson concludes with a problem set to reinforce the concepts learned.

What is a net in the context of three-dimensional figures?

• A two-dimensional representation of a three-dimensional figure

• A mathematical formula
