This lesson is based on the MTLT article, “Supporting LGBTQ+ Students in K-12 Mathematics” by Brandie E. Waid. In this lesson, students identify lines of symmetry for various symbols, create line-symmetrical figures and examples and non examples of images that have lines of symmetry, and analyze and discuss similarities and differences between their identify and that of their classmates.
