This is a photo of a handout from a special ed conference shared by Dr. Shaunita Strozier (email@example.com) of Valdosta State University. It shows the use of algebra tiles to provide a concrete level of the concept of an equation and solving the equation. The photos on the left show the R or representational level of the concept. Her approach is called SUMLOWS which is an acronym explained in this handout.
