This work presents a didactic proposal for the classes of affine and quadratic functions in elementary school. From our experiences in the teaching profession, we noted that the study of this content requires experimentation and contextualized activities. The study of affine and quadratic functions in basic education is of great importance for abstraction capacity development, solving practical problems and helps to get skills of comparing results, recognizing the characteristics of these functions. Our work is not intended to define affine and quadratic function, but to develop the perception ability of the results that leads to graphs and charts building and can be confirmed using the GeoGebra software. This activity was implemented in two classes of the ninth year of elementary school at Colégio Batista Brasileiro in Bauru. To do this we need four classes of 100 minutes and 1 class of 50 minutes. This is a didactic sequence that requires the use of computers and of the GeoGebra software.
