Uma contribuição ao ensino do cálculo de raízes quadradas e cúbicas.

Abstract

In this work, we propose a rescue methods for calculating square and cube roots of a real number which, although very old, may be unfamiliar to some of the math teachers. To facilitate the understanding of these methods, we seek to justify and explain the procedures involved. Such methods, allow the student, finding exact roots or not, results without decorating, more significantly, through arithmetic operations. To this end, we developed a propost of learning activities that allow the use of the term and closing sequences to obtain results dynamically, promoting understanding the concept of root extraction, more specifically the square root and cube root.
