Algumas possibilidades para o ensino da área do círculo

Abstract

This paper presents a study developed at the Federal University of Uberlândia-UFU, around two methodological perspectives: The Investigative Class and the Teaching Activity. The study in question was intended to answer the following question: What are the differences and similarities between the investigative class and the teaching activity in the work with the mathematical concept: area of the circle, for Elementary School students? The objectives of this research were: a) to analyze the impacts that the mathematical investigation and the teaching activity can provide in the teaching of the area of the circle; b) make a comparative study between these two methodologies; c) to promote improvements in the methodological practices of teachers in the classroom; and, d) to make an effective proposal of these two proposals of the school environment, in order to have an analysis of the theory with the practice of teaching. A teaching activity was developed on the area of the circle, using elements of the history of mathematics and the game as a resource triggering a problem situation, as well as an investigative class on the circle area, using manipulative material with students of the 9th grade of elementary school. It is hoped that the reports and analyzes discussed in this text can be of great contribution to the training of teachers and to the improvement of the teaching of Mathematics.
