Uma visualização e a representação planar de sólidos na geometria espacial

Abstract

The aim of this work is to present a didactic proposal for the development of visual didactic skills and planar visual representation of three dimensional solids. The central motivation is to provide students the possibility of a better understanding of relations between tridimensional objects and their planar representations, topic present in exams of assessment national and, also, in the exercise of various professions and in function artistic productions. At the same time, as aureus is our desire to attract the students to study of Geometry, we will expose everyday situations where the student realized how big is the presence of ther applicability of this branch of Mathematics is so appealing that the Geometry. We exemplify moments, places, objects, animals, professions etc, to make it clear that presence natural of this material, senders us the importance you master, at last of basic geometry concepts. Still in the same order, and fulcrum theorists as Jean Piaget and Van Hiele, we could not us pilfer of exposing the use of concrete materials and manipulative in teaching of Geometry. For all this, more attractive, awaken a different vision on the student and make him realize that Mathematics, especially the Geometry, is more than ready formulas and analytical calculations that converge to a single number.
