Resumo
Os materiais manipuláveis são indicados para auxiliar as crianças na passagem do concreto para o abstrato. Isso, aliado ao fato da dificuldade dos alunos na geometria ao utilizar o ensino tradicional em anos anteriores, motivou a utilização de materiais manipulativos no ensino de Geometria Euclidiana Plana. O trabalho foi desenvolvido com o 9° Ano da Escola Municipal Marciano Maciel da Silva, Tanabi/SP, com 24 alunos que estavam com dificuldade na compreensão e fixação dos conteúdos de geometria. O mesmo envolveu as atividades práticas do capítulo 3. Utilizamos materiais manipulativos a fim de que o alunado se tornasse capaz de compreender conceitos de Geometria Euclidiana Plana. O objetivo deste trabalho é apresentar a teoria de Geometria Euclidiana Plana, em particular, áreas de regiões poligonais elementares, comprimento de circunferência e áreas de regiões circulares, a qual corresponde às atividades práticas desenvolvidas no 9º ano, e os resultados obtidos com relação à aprendizagem dos alunos com o uso dos materiais manipulativos. Observou-se que o trabalho com materiais manipulativos cumpriu o seu papel de capacitar e engajar os alunos para a compreensão e estudo dos conteúdos ministrados.
Manipulative materials are essential to help children in the transition from concrete to abstract. That, besides students’ difficulty in geometry using the traditional teaching in previous years, motivated the use of manipulative materials when teaching Euclidean Plane Geometry. This work was developed with the 9th grade of Marciano Maciel da Silva Municipal School in Tanabi, SP, with 24 students who presented a great difficulty understanding and fixing contents of geometry. The same involved practical activities of Chapter 3. Manipulative materials were used so that the students would be able to understand Euclidean Plane Geometry concepts. The goal of this paper is to present the Euclidean Plane Geometry theory, particularly, areas of elementary polygonal regions, circumference length and areas of circular regions, which concerns practical activities developed in the 9th grade, and results obtained in relation to students learning through the use of manipulative materials. It was observed that the work with manipulative materials fulfilled its role of enabling and engaging students to understand and study the content presented.
