Among the contents of mathematics worked in Basic Education it is possible to assert that the teaching of the rational numbers, especially in fraction form, is still quite deficient, being presented through calculation strategies, since the study of this content provides diverse everyday applications favoring the contextualization of Mathematics teaching. Thus, this research aims to analyze the methodological approaches about the concepts and meanings of fraction on the textbooks, in order to identify which contributions and implications of this methodological resource about this content to the teacher practice, if the same respond to official instructions and if the methodology used in this resource favors the motivation and the learning.
