In the light of the difficulties most first-year students at high school face regarding the learning of mathematics contents, this study proposes some activities aiming at teaching square function using the win-plot software as a tool. At the beginning these activities were designed to be applied in the first year of the PROEJA course (a high school course integrated to a technical one for adult learners) at Instituto Federal do Tocantins, however it can be useful for any student who is learning square function. The activities proposed do not intend to replace the formal and algebraic teaching of the subject, yet they aim to offer teachers and students an interesting option to build graphs in an interactive and agile way. Through graph animation tools, we intend to make some relations between the parameters and the behavior of the graph, always presenting the mathematics explanation of the relation observed at the end of the activity.
