Cross Sections

Curated and Reviewed by Lesson Planet

Young visual learners explore different cross sections of 3-dimensional objects. First, cross sections of cubes are explored by using an interactive flash activity. This is then extended by looking at cross sections of spheres, cylinders, and cones. This is a good introductory activity.
