Seleção de materiais didáticos para um laboratório portátil de matemática para o ensino da unidade temática números segundo a BNCC dos anos finais do ensino fundamental

Abstract

The aim of this study was to select teaching materials to compose a Portable Mathematics Teaching Laboratory (LAPEM), focusing on the Numbers Thematic Unit (UTN), according to the guidelines of the National Common Curricular Base (BNCC) for the final years of elementary school. The need for a LAPEM, a concept adopted by Lima (2018), is justified by the frequent lack of permanent physical spaces for mathematics laboratories in schools, which can discourage teachers interested in developing more concrete and dynamic pedagogical practices for teaching numerical concepts. For this purpose, the selection of teaching materials was carefully planned to cover knowledge objects and specific skills for the 6th, 7th, 8th, and 9th grades, with a specific material for each grade. It is concluded that the LAPEM presents itself as an effective alternative to overcome structural challenges faced by educational institutions, in addition to promoting a more creative pedagogical approach centered on student participation. The proposal aligns with the BNCC principles, favoring contextualized, active, and meaningful learning, and the development of essential competencies and skills. It is expected that this study will positively influence mathematics teachers, offering them the possibility of creating and using a LAPEM, contributing to students' better understanding.
