A EDUCAÇÃO MATEMÁTICA E O ENSINO DE ÁLGEBRA NA PERSPECTIVA DE DESENVOLVIMENTO DO PENSAMENTO ALGÉBRICO

This article discusses the teaching of algebra from the perspective of the development of algebraic thinking, based on activities in the 6th Mathematics textbook. Year in line with Mathematics Education. We investigated how the teaching of problems involving natural numbers and their ability to develop algebraic thinking is considered, considered a special way of thinking, important in the construction of mathematical knowledge. We sought, supported by the Anthropological Theory of Didactics, ostensive and non-ostensive objects that could be evoked in this algebraic education. It focused on mathematical activities of establishing relationships, in the processes ofgeneralizing, modeling, operating with the unknown as if it were known and building meaning for the algebraic symbolic language. The analyzes point out that algebraic education based on problem solving activities aiming at the production of meanings is a path for the development of algebraic thinking, due to the relationships and connections that it needs to establish in order to solve them, and thus for algebraic and mathematical learning.
