This lesson is based on the MTLT article, “Inquiry + Math Workshop Model = Success!” by Tutita M. Casa, Kathryn O'Connor, and Emma Dearborne. The lesson demonstrates the use of a workshop model that engages students in developing strategies to solve an authentic multiplication task.3-5
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.
