The geogebra software as a tool to facilitate the construction of knowledge about the center of symmetry of a shape at the 6th-grade

This article presents a teaching design for the concept of shapes with a center of symmetry, the center of symmetry of a figure with the support of GeoGebra software. The "dynamic" features of the GeoGebra software have facilitated students in the process of acquiring knowledge and simultaneously created opportunities for students to form and develop mathematical competencies.
