Construções Geométricas: uma proposta de ensino utilizando régua, compasso e dobraduras

Abstract

The present work discusses the importance of geometric construction activities for the development of students in Geometry. In this perspective, initially, a survey is made about what the Cammon Base National Curriculum (BNCC) proposes, as essential contents, in the skills of Geometry on geometric constructions in the final years of Elementary School. Based on the BNCC guidelines, an analysis is made of three collections of Mathematics textbooks, destined for the final years of Elementary School, on their adequacy to the guidelines of the Common Base National Curricular. In addition, the work presents the geometric constructions that are part of the list of guidelines of the BNCC, added by others of relevance in the consolidation of the content. Finally, a proposal for geometric construction activities with the use of folds is suggested, presenting the use of folds as an auxiliary and diversified way of working with geometric constructions.
