In this article we present a study related to the arguments made by elementary school students in the resolution of geometric problems that contain a graphic representation. In particular, their arguments were analyzed through the argumentative model of Toulmin, which allowed its reconstruction from the interventions made by them. Thus, the results indicate that in the resolution of geometric tasks, elementary school students base their arguments on visual characteristics of the mathematical object under study, from formulas or properties belonging to school mathematics.
