TEACHING ANGLES AND POLYGONS USING GEOGEBRA SOFTWARE

Abstract

The objective of this work is to describe a didactic-pedagogical sequence developed to teach angles and polygons in an 8th grade class of Elementary School of a state public school in Palmeira dos Índios, Alagoas, Brazil. The sequence is part of the Extension Project "Mathematics and Active Methods" and addresses some common difficulties in teaching geometry, such as the abstraction of formal concepts and the lack of understanding of students of the connection of these concepts with real situations. Studies indicate that the use of digital technologies facilitates visualization and interaction with mathematical concepts, promoting more dynamic and meaningful learning. In view of this, the sequence, applied in four classes, involved activities contextualized to the sport, using the GeoGebra software. The results show that, although some students still face difficulties, the interactive and contextualized approach improved engagement and understanding of formal mathematical concepts, especially geometric ones.
