| Abstract | Piecewise linear functions and story graphs are concepts usually associated with algebra, but in the authors' classroom, they found success teaching this topic in a distinctly geometrical manner. The focus of the approach was less on learning geometric concepts and more on using spatial and kinetic reasoning. It not only supports the learning of (what is now called) algebra but also recasts algebraic concepts and ideas in geometric terms. The classroom activity the authors describe was influenced by the Connected Mathematics Project middle school textbook "Variables and Patterns," for which they designed technology-based support using The Geometer's Sketchpad[R]. This article discusses how students develop the ability to describe functions in a geometry context by focusing on slope and using dynamic software. (Contains 6 figures.) (ERIC). |
