Explorando um material didático: Desvendando os quadriláteros

Abstract

From the BNCC onwards, the teaching materials used in schools across the country underwent a reformulation that affected the didactic and mathematical organization of various mathematical objects. This reformulation went beyond textbooks and affected all teaching materials designed for teaching and learning in basic education. In view of these changes, we investigated in general how the content of quadrilaterals is included in an elementary school booklet for the final years of a private school in the city of Aquidauana-MS. The intention was to present the organization presented by the SAS network in relation to the quadrilateral object of study.
