A construção dos números naturais no ensino fundamental

Abstract

It is observed that the construction of natural numbers are worked since elementary school, from natural to real numbers. Therefore, this study aimed to reflect on the methodologies for the construction of natural numbers sets, as well as to recommend proposals regarding the procedure for teaching and learning natural numbers in Elementary School. The methodology applied for the development of this study was the literature review. As the construction of the numerical system occurs through the relationships developed by the subject, it is recomended to help by suggesting activities, games, etc., which may benefit the establishment of these relationships, and, in such a way, I was developing the logical-mathematical reasoning of the students through a reflective abstraction.
