Resgate da geometria no ensino fundamental (uma proposta de sequência didática para o resgate de parte do conteúdo geométrico no 8º ano do ensino fundamental)

Abstract

This dissertation deal with a didactic sequence that aims to contribute to the rescue of basic geometric concepts that have not been seen and / or learned by students from 4 to 7 years of elementary school. The motivation for this approach is due to the perception of lag content relating to this topic of mathematics with students from 6th to 9th grades of elementary school. Through this didactic sequence it is intended to promote the rescue of some basic geometric concepts such as primitive concepts (point, line and plane), line segment, midpoint, angles, parallel lines and perpendicular lines, polygons, triangles, quadrangles, sum of the internal angles of a triangle, perimeter and areas thereby helping the students to cover some conceptual gaps geometry and also tu help mathematics educators to face this problem.
