Demonstrações visuais no ensino de matemática

Abstract

Starting from a definition of mathematics proficiency and motivated by give opportunity this proficiency to students of elementary and high school this research seeks to show visual proof as a tool to achieve that goal. Introduces the general concept of visual proof from what many researchers classify as visual representations and their use within the logical structure of a mathematical proof. Researches indicating appear because visual proofs can be useful tools in the classroom, and characterized as a visual proof can be effective in the teaching of mathematics. With those reasons are presented six visual proofs with usage suggestions in the classroom, with elementary and high school content. These suggestions bring changes based on authors underlying this work with the intention to expand their educational potential, such as use of dynamic image, color, repetition and manipulatable material.
