* I use this as a supplement lesson for Math in Focus. MIF does not address the common core standard 2G.1 to fidelity, so I use supplement lessons to teach it.
This Powerpoint lesson teaches the concept of symmetry. It reviews the plane shapes taught in a previous lesson (triangle, square, rectangle, pentagon, and hexagon) It uses these shapes to discuss lines of symmetry.
It includes a hands on practice activity and an exit slip to assess students understanding of symmetry.
