Abstract: This paper describes mathematics problems that can be made in Geogebra using Polya’s problem solving phases. We describe three ways to use Polya’s phases in Geogebra: explaining, exploring and modeling. As an example, we focus on the derivative of a function using a dynamic worksheet. We present an outline for secondary school teachers to use to explain the geometric interpretation of a derivative at a given point. The five stages of symbolism from Moreno-Armella, Hegedus and Kaput are used to describe the interpretation of the dynamic worksheets. Using these techniques, teachers can help students to visualize mathematical objects and to develop a visual understanding of mathematics concepts and the relationship between them.
