Laboratório de matemática sustentável: o uso de materiais recicláveis como estratégia para o ensino de geometria no Ensino Fundamental

Abstract

This study aims to contribute to the implementation of a sustainable mathematics laboratory in a public elementary school in the city of Bacabal-MA, where students will have a space for learning and environmental awareness. The purpose is to promote sustainable geometric education among students, develop skills related to logical reasoning, and explore geometric concepts (shapes, areas, perimeters, solids, symmetry) using recyclable materials. For this research, data was collected through specific questionnaires applied to students from the 6th to the 9th grade of the final years of elementary school, and analyzed through a discussion circle addressing students' questions. Over time, difficulties were noted in a logbook. The construction of mathematical objects took about fifteen workshops, and the students were able to absorb the learning clearly, as they were the protagonists of the mathematical constructions. Therefore, it was possible to observe that the implementation of a mathematics laboratory in a school brings satisfactory results to student learning, as it elevates the level of learning from something abstract to something concrete and improves school performance. Therefore, we observe that this work offers a replicable model for a mathematics laboratory, with guidelines for implementing and cataloging activities aimed at improving geometry teaching.
