    This work aimed to carry out an investigation in the approaches developed on the set of irrational numbers in the final years of elementary school. The methodology used is of a qualitative and technical nature of documentary analysis. Therefore, it does not need immediate interference in empirical practice and does not impose immediate interaction of the construction of theory and practice. In this way it was observed how the teaching of these numbers is exposed to these students and how this subject is approached in the textbooks of mathematics of this series. As support for the work is presented the exposition of mathematical procedures of the elements pertinent to the study and analysis of literatures in two collections of primary school mathematics. An alternative model is proposed. There was a static and repetitive approach to the teaching of irrational numbers, which is summarized in a didactic material without changes related to this approach or methodology applied to the teaching of rational and irrational numbers.
