Resoluções visuais e materiais didático-pedagógicos lúdicos no ensino de matemática na educação básica

Abstract

The present work is a collection of three articles. The first article was written in collaboration with Hilario Alencar and Milena Farias. The other two articles were written in collaboration with Milena. In the first article we constructed visual resolutions of some mathematical problems, involving algebra, geometry and trigonometry, which are known in Basic Education. In the second article we present the experience of Profmat graduates at Ufal who teach Mathematics in Alagoas and use ludic didactic-pedagogical materials as a didactic resource. In the last article we present a visual solution to the following problem: What is the relation between the area of the square inscribed in a semicircle and the area of the square inscribed in a circle of the same radius?
