Estudo do círculo através da construção de mandalas

Abstract

This work presents a proposal to study circles, their area and length, through the design and construction of mandalas. We present a theoretical grounding on these themes and report a didactic experience with students of the 7th grade in the Mathematics discipline of an elementary school located in the city of Bayeux - PB. First, we applied a questionnaire with the students to evaluate their previous knowledge about: point, line, plane, flat figures, symmetry and other related concepts. Subsequently, after exposing the necessary content, we focused on the exploration of geometric structures inscribed on the circumference with the generation of mandala models. There were individual and group activities, with mandala design and construction using crepe paper. The results show that this approach enriches the learning of geometry because it makes clear its relationship with everyday objects.
