Elementos matemáticos existentes no cotidiano de um profissional técnico da cagepa.

Abstract

The present work aims to discuss the need to develop mathematical teaching practices in a contextualized way with the students' daily life in the northeastern semi-arid region, seeking to lead them to greater success in the teaching and learning process. Therefore, as a demonstration for a possible contextualization of mathematics, we use mathematical elements of the daily life of the technical professionals of CAGEPA - Companhia de Água e Esgotos de Paraíba, to envisage the promotion of its teaching in schools, approaching contexts of the daily life of the population. We start from the reality that we live in, that is, a time of long drought and a crisis in the water supply in the Western Cariri of Paraíba and this problematic can come to generate several contextualizations for the teaching of mathematics, properly, since it is a situation lived daily . We know that some expressions emerge in the media, on the talk wheels, etc., where there are contained in them several mathematical elements spoken daily, such as: "Dead volume", "10% capacity" and several others and even the very word "rationing" ". So, the purpose of this article was to show scenarios of contextualization from the reality of a professional category, closely interlinked with the reality of the semi-arid Paraíba. It was possible to show that the scenarios, together with the analysis of a semistructured questionnaire applied to the population, which are several elements for use in the classroom, which makes it possible to bring the mathematics of daily life, professions and school into a common goal , which is learning consistently.
