摘要：This paper presents a simulation experience with GeoGebra lived by two average level high school students from Venezuela. Specifically, it describes the way in which students solve the task of representing a phenomenon with the software. During the simulation, the interpretations of being part of a whole, as well as distribution and fractions operator, took place and helped students to create and validate technics to locate characteristic points of the geometrical figures associated with the phenomenon treated. The connection between the different interpretations and other mathematical concepts were also present. Regarding to GeoGebra, it is highlighted the use of the grid as a graphic reference that supported the reflections of the students during the experience.
