Planes & the Polyhedron Lesson Plan

Instructor: Adrianne Baron

Adrianne has taught high school and college biology and has a master's degree in cancer biology.

Your students are around planes and polyhedra at almost any given time. Your students will learn what a plane and polyhedron are as they watch a video, identify planes and polyhedron and take a quiz.

Learning Objectives

At the completion of this lesson students will be able to:

  • define plane
  • identify planes in different objects
  • define polyhedron
  • identify polygonal faces on various polyhedra


1 - 2 hours

Curriculum Standards


Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.


  • Computer with projector
  • Copies of the lesson quiz
  • Printer paper
  • Colored pencils
  • Several different polyhedra (Place a few different ones at 5 or more stations around the classroom. Write a number for each station. Create an inventory sheet for each station by writing the station number and what objects you put at each station to help you later with grading.)
  • Three-dimensional objects that do not classify as polyhedral (place a couple of these at each station in the room as well)
