This study sought to analyze the development of the subject Combinatorics in Math Textbooks of Elementary School in the light of the Theory of Conceptual Fields and some research that approach this topic. A collection if each level of Elementary School was selected - early years and final years - between those that were approved by PNLD 2013 and following year, respectively. Through the mapping of all activities and the Teacher's Guide, was possible to realize that, although the combinatorial problems are present and there is a good variety of symbolic representations, it's necessary to explore the perception of the invariant properties that are involved in Combinatorics and to formulate specific guidelines that makes the teacher capable to develop this subject effectively with the student, mainly the teacher of the early years, who generally, don't have in-depth training about this specific knowledge.
