Dobradura em geometria plana: aplicações metodológicas no ensino médio

Abstract

Mathematics is a science that allows various applications in the development of its areas, among these areas, there is geometry, which consists of relating geometric shapes and mathematical calculations, in order to improve the development of the world. Mathematics in general is said to be difficult by students, and many are the causes for these difficulties. The general objective was to evaluate the effectiveness of the use of foldings for the teaching of flat geometry, for students of the 2nd year "C" of ceti pinheiro machado school. And as specific objectives a) to investigate the effectiveness of teaching materials for the teaching of geometry; b) to analyze the difficulties of 2nd year "C" students in studying flat geometry; d) Solve flat geometry issues using folding. The research was based on authors such as Da silva 2014 on methods for teaching mathematics and PCN to show the relevance of geometry teaching. A 2nd year high school class was selected, so the research was developed in 8 meetings. Satisfactory results were obtained and it was noticed that the reinforcement of flat geometry is quite relevant for the teaching of spatial geometry
