Ensino-aprendizagem da geometria usando materiais concretos

Abstract

This paper presents some methods for teaching and learning of geometry, reflecting the existence of different strategies of teaching, with the purpose to seek a more meaningful teaching of mathematics, taking a critical and autonomous thinking and thus triggering improvements in geometric reasoning and spatial awareness , no more leaving aside the history of geometry, because this encourages us to the paths already trodden by mathematicians and ideas previously applied, and still teaches and helps in our day to day. In teaching geometry uses up much of the language and symbolism and the textbook in turn reduces the geometry formulas without interacting with reality. However, some textbooks are being rewritten, bringing a significant learning. Faced with these problems related to learning of geometry, were authors who have investigated appropriate methods for understanding various geometrical concepts, transmitting knowledge through concrete materials in context and integrated with reality and so have been developed and tested new methodologies that involved situations conducive to discussion and reflection, such as visual-tactile activity, such as polyhedral with straws, folding and Cortez of soap, which include creation, handling and obtaining the geometrical knowledge, making the geometry joyful, creative and useful, thus ensuring the participation and student interest.
