Generally, at the elementary school early years, activities focused at the perception of geometric forms and in the final years and teaching of geometry tends to be more theoretical. However, it is important that experimental activities and conceptualization be present at any level of education. Thus, in this article we present and discuss a sequence of activities related to the study of quadrilaterals that was carried out by fifth year students of elementary school. They have obtained the figures that represented each type of quadrilateral by means of folds and cutouts, made artistic works with these figures, explored their properties from the symmetry axes, socialized their discoveries, then built quadrilaterals in the geoplan and represented the constructions realized on dotted paper. The research has achieved that manipulation is possible and necessary since the earliest years, so the construction and the drawings be worked in an articulated way with the theoretical knowledge of the geometry. It was also verified that interactions and negotiations of meanings play a fundamental role in the learning process.
