Aprendendo geometria explorando o contexto e realidade do litoral do Rio Grande do Norte

Abstract

In this work, carried out at the Vicência Castelo Municipal School, located in Pipa, Tibau do Sul-RN, we propose an innovative approach to teaching geometry, valuing the students’ practical experience. We begin the text by exploring the concept of ethnomathematics and then highlight the relevance of meshes in the construction of geometric figure concepts, using the cast net as the object of study. Our investigation focuses on the study of plane geometric figures, anchored in the fishermen’s technique for repairing nets. We propose practical challenges with meshes, developed by the author of the dissertation based on direct experience with fishing tools. In addition, we examine the exploration of spaces and shapes from aerial images and the construction of floor plans, using these perspectives for a better spatial understanding. The approach to geometric solids is facilitated by the use of GeoGebra and Tinkercad software, as well as by building models with beach sand. The activities are monitored in detail through a systematic study routine, and the results of the students’ performance are presented in graphs, showing the impact of practical activities based on their experience.
