Introduce proofs in your classroom using hands-on activities that will help your students understand the basic idea and format of proofs. This lesson comes with a powerpoint to assist you and the students with the lesson. The other pieces of the lesson are seen below:

  • Lesson Plan - Step-by-step guide on how to use the resources.
  • Silly Proof Example - Can be used as a bulletin board.
  • Matching cards with properties, definitions and postulates
  • Algebraic Proof practice
  • Geometric Two-Column Proof Scramble –rearrange statements and reasons
  • Geometric Proof practice
  • PowerPoint Lesson Helper
  • Paper Quiz and a Self-grading Google Quiz
  • Sneak Peek at the Next Lesson!

It takes more than one lesson to teach proofs. It is ongoing throughout the year. This lesson is a starter lesson so that proofs can be used continually. This resources focuses on two-column proofs! I introduce the other proofs as I go.

All my lessons have been classroom tested. I am continually improving my lessons, so check back often for updates!

This Geometric Proof is also available in money saving bundles!
