Dissertação (Mestrado Profissional em Matemática em Rede Nacional) - Universidade Federal de Goiás, Catalão, 2015.http://repositorio.ufcat.edu.br/tede/handle/tede/4722This work aims to recognize methods and methodologies that seek remedy some di culties in the teaching and learning process in the geometry branch. These methods were applied to a class 7 year of a school on the outskirts of Federal District in 2014, and has the theme "Playful Activities for Teaching Geometry. "With this theme, a brief historical overview was presented on geometry. It then sets a study of this branch of mathematics, speci cally content and properties of triangles. Subsequently described the application site this work and the methodologies used were; concrete material and writing mathematics. Finally, the application is analyzed these methods and methodologies in room school as well as the results achieved. It is concluded that with the methodologies adopted the results were satisfactory, as the students were involved signi cantly.application/pdfAcesso AbertoGeometriaTriangulosRedacao MatematicaMaterial ConcretoGeometryTrianglesMathematics WritingConcrete MaterialCIENCIAS EXATAS E DA TERRA::MATEMATICADissertação
