Visualização geométrica: uma habilidade para ser valorizada no ensino fundamental

Abstract

The present study aims elaborate a sequence of teaching activities, using manipulative materials that develop geometric thinking in view level. The research intended to answer the following questions: how is the ability of the fundamental level student to visualize geometric figures? How can we improve their ability to geometric view? Therefore, it was developed and applied sequence of activities. The intervention was performed in the elementary and middle school Severino Félix de Brito, in a 9th grade class of elementary school situated in Itapororoca – PB. We took as a theoretical referencial, authors like Van de Walle (2009) e Paiva (2003). To develop activities, we adopt the conception of Van Hiele model of geometric thinking. In the first activity the student built a structure with cubes made by the researcher and drew two views indicated in the activity. In the second activity the student drew a picture of a box of toothpaste empty and in the third activity the student painted solids in perspective designed by the researcher and calculated the number of parts required for their composition. After completing each activity was applied a questionnaire to assist in posterior analysis. The analysis of those activities revealed that the students have low ability in geometric view while they show interest and capability, requiring a work that seeks deepen the knowledge about geometric view.
