Utilizando material concreto para resolver o teorema de Pitágoras no EJA

Abstract

One of the greatest mathematicians of all time Pythagoras, undoubtedly was one of those responsible for the advancement of mathematics, dedicated the study of philosophy, astronomy and geometry. One of his major works was solving practical problems in the right triangle, was the first man to He was the first man to prove the theorem, named after him, that the square of the hypotenuse is equal to the sum of the squares of its catheters. Mathematics teaching provokes different sensations, both for teachers and students. teachers and students alike: on the one hand, a very important area of on the other, dissatisfaction with the negative results or success with the positive ones. the positive ones. However, every teacher knows that facing the challenges in the classroom is not easy. is not at all easy. During the training courses for the degree in mathematics, it was noticeable to observe a great difficulty of students regarding the applications of mathematics in everyday life, it was noted that students have great difficulty in the study of Geometry, a subject that is constantly present in our lives. our life. In the search for improved methods for teaching mathematics in the classroom, the classroom, the use of concrete material to prove a demonstration becomes an interesting interesting and facilitating methodology so that students can understand the usefulness of mathematics, and how it is related to the world, learning to develop and build their own knowledge. The present work sought possible improvements for the teaching of this subject, using concrete material to perform geometric demonstrations geometric demonstrations, thus making it a facilitator of mathematics teaching, so that students can realize how students can realize how the Pythagorean theorem is present in our lives, as well as their respective usefulness. Thus, it was verified if the methodology used by means of manipulative manipulatives the teaching of mathematics was satisfactory, evaluated all the possible characteristic of the difficulties of teaching in the classroom.
