Lesson Plan
Simply Symmetry!
Symmetry is everywhere, but it's often hard to notice. This lesson explores a few ways to identify it. By folding and making mirror images for different shapes, students will discover a new world of symmetrical figures.

Learning Objectives
- Students will be able to identify symmetrical figures, draw lines of symmetry, and explain why or why not a figure has symmetry.
Introduction
(5 minutes)- Display the image of the butterfly.
- Ask the class to share some things they notice about the image. Some guiding questions you could ask are: What are the colors of the butterfly's wings? How are the wings shaped?
- Once students touch on the idea that the wings match in some way, introduce the word "symmetry." Explain that something has symmetry if it can be split into two mirror-image halves. For example, a butterfly is symmetrical because you can fold a picture of it in half and see that both sides match.
