Ensino da geometria espacial construindo superfícies poliédricas com dobraduras

Abstract

This work presents a differentiated proposal, from the one that we are used to, teaching geometry space. The class was applied in the group of third year in a State School of Rio Grande do Sul high school, name Marquês of Maricá, the study started from presupposition of urging the students' intuitive capacity as for the volume calculation of the polyhedrons. At the beginning a questionnaire was applied to evaluate the students' previous knowledge in relation to geometry, after it was developed a classusing flasks in different ways and sizes where were analyzed and discussed which were polyhedrons, which polyhedron had larger and smaller volume of them, afterwards each student made a square prism using the folded technique and starting from this prism to study the volume in a concrete way was introduced. The last activity with the students was to show the relationship between the prism volume and Pyramid. At the end of the work other questionnaire was applied to evaluate the students development and the knowledge and if the objectives were reached.
