O ensino de poliedros de Platão com materiais concretos: uma experiência com alunos do 6º ano do ensino fundamental

Abstract

This study's main focus was to investigate the potential of using concrete materials in playful activities involving Plato's Polyhedrons in a sixth-grade class at the Francisca Almeida Municipal Elementary School, located in the urban area of Mamanguape, Paraíba. This required a bibliographical survey to understand how concrete materials work, the Geometry Teaching Laboratory, and how to encourage geometric, spatial, and critical thinking in students to consolidate their knowledge of geometry. It is also important to review the entire history of geometric studies described in the Common National Curricular Base document, highlighting the relationship between the skills students should develop and the objects of knowledge throughout the school year. The methodological procedures, which presented the research context, its instruments, and its stages, were also important. This research concluded that concrete materials are indeed helpful for teaching. However, simply having them in hand isn't enough; it's also important to have a grasp of what's being taught and how to visualize geometric knowledge in such concrete materials and for such a purpose. Finally, we emphasize that the use of concrete materials engages students during learning and sparks interest and curiosity when investigating geometric problems throughout the class, which fosters autonomy and contributes to student development.
