Brief Description: In this lesson, students will explain how they know whether a sample object is or is not symmetrical.

Know Before You Start: Make sure to introduce the term line of symmetry if they aren’t familiar with it yet.

Hook: Read and discuss the sample comic.

  • What does the term symmetrical mean?
  • Who do you agree with?
  • Why?

Activity:

  • Using the sample comic as a guide, have students create a three-panel comic depicting an object or building. 
  • The comic should include the following:
    • Panel 1: Using the “Background” tab, have students select a scene showing a building, geographical feature, or object.
    • Panel 2: Explain whether or not the sample shape has a line of symmetry.
    • Panel 3: Describe where that line is, and whether it is vertical or horizontal.

Closure: Have students conference with a partner to see if they agree with the justification each provided in their own comics.

Differentiation:

  • Assign specific backgrounds to students as necessary.
  • Have students complete the Symmetry Comic with a partner if helpful.
