O uso de materiais manipuláveis na geometria plana das séries iniciais: algumas experiências com Tangram

Abstract

Knowing the geometric shapes and their characteristics is something that is far removed from the reality of students in the initial grades, a reality that may occur due to the lack of interest of students in mathematics classes or even by the methodology used by the teacher. Many teachers, in the flat geometry classes, have difficulties in transmitting the content, either due to the lack of mastery and didactics, or due to the lack of resources in schools for a better development of the classes. Therefore, this work aims to present the use of manipulable materials as a playful tool for flat geometry classes in the initial grades, through some experiences with Tangram, making the classes dynamic, awakening the student's autonomy in the construction of knowledge and developing your creativity.
