Situações de ensino de geometria utilizando materiais manipuláveis para o 3° ano do ensino médio

Abstract

The present work was developed in a public educational institution, downtown Curitiba – PR, with students from the 3rd year of high school. In order to propose teaching situations that would help the understanding of geometry-related contents, through the use of manipulable materials and exploring visualization by the students. Manipulable materials were used só that, from the manipulations, the students understood the area formulas of geometric figures, calculated the prism volumes and presented a proposal for a new prism with a determined volume. For this, the action research was used as methodology, which aims to improve the work developed. In order to relate visualization and mathematical content, we adapt existing teaching situations, present a didactic sequence that enables the use of manipulable materials in the last year of high school.
