Uso do material concreto nas aulas de geometria espacial na 3ª série do ensino médio

Abstract

In this work we present a planning proposal for spatial geometry classes for 3rd grade high school classes. The planning was based on bibliographical research on the relevance of the use of concrete material in spatial geometry classes, in order to support teachers who are interested in presenting more attractive and effective classes. The planning is presented divided into five moments, in which we present ways of working the content, detailing in each one the activities that can be developed, exposing step by step each one of them always focused on the result to be achieved based on the thoughts and studies of philosophers and researchers of Mathematics Education. Studies developed on this topic show that the use of concrete material has been an important resource for the good development of the teachinglearning process, as it allows an intervention in mathematical content through objects used by students in their daily lives. In our proposal, we try to show that the use of concrete material by students aims to give them autonomy so that they can develop new ways of understanding the content, the teacher then becomes an intermediary functioning as a link that connects the abstract content to the object that student is manipulating. With this, we seek to build a less mechanical learning, avoiding the application and memorizing of formulas and giving meaning to the content in the daily life of each one of them.
