Unit 6, Lesson 19# Understanding Three-Dimensional Figures

EngageNY 45 min(s)

In this lesson, students examine figures built out of unit cubes. Slices are made at each level of the figure so that each slice is actually between layers of cubes. Students describe three-dimensional figures built from cubes by looking at horizontal slicing planes. In Lesson 19, students take an easy approach to thinking of a figure in slices.
