Atividades com recursos manipulativos para o ensino de geometria espacial na educação básica

Abstract

The present work has, as its central theme, the proposal of manipulative resources for teaching three-dimensional solids in Spatial Geometry, using low-cost materials. Our overall objective was to present and discuss activities that utilize concrete materials in the context of Spatial Geometry. To achieve this goal, we had specific objectives: Identify mathematics teaching proposals that make use of manipulative teaching resources aimed at Basic Education; and select proposals based on Spatial Geometry using concrete materials and relate these proposals to learning objects and mathematical skills presented in the Base Nacional Comum Curricular (Brasil, 2018). Our study was qualitative in nature, bibliographic and documentary, since the activities were taken from books and scripts developed by the Probex Project team. The theoretical framework of the research was based on the Van Hiele Theory for geometric thinking and the Knowledge Objects and Skills of the BNCC (Brasil, 2018), as it is the most recent document, but we also addressed the PCN (Brasil, 1998) and manipulative materials for teaching Spatial Geometry (Smole; Diniz, 2016). Our survey was developed using proposals for manipulative teaching resources and some exploratory activities that encourage greater student participation and assist in the development of geometric thinking.
