THE GEOGEBRA SOFTWARE AS A TOOL TO FACILITATE THE CONSTRUCTION OF KNOWLEDGE ABOUT THE CENTER OF SYMMETRY OF A SHAPE AT THE 6TH-GRADE

In the 2018 curriculum for general education, the Geometry and Measurement module at the middle school level supplements visual geometry content. Teaching visual geometry, especially the concept of shapes with a center of symmetry, the center of symmetry of a figure at the 6th-grade level poses many challenges for teachers. 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.
