This study aims to emphasize the importance of using Problem Solving as a focused tool for solving significantly the most diverse mathematical content. For that, it was researched different approaches of Problem Solving and It was analyzed the book "Tudo é Matemática" written by Luiz Roberto Dante and compared with the notebook (the student book) the Curricular Proposal from State of São Paulo, both of them are specific for taught at the 8th-grade, focusing specifically on Notable Products. The theoretical framework was based on the ideas of Chevallard, regarding the Didactic Transposition Theory which focuses on the relation between mathematical scholarship and mathematics teaching, establishing a necessary gap between scientific knowledge and the knowledge built in the classroom. The analysis of the courseware was focused on the techniques of Content Analysis from Bardin, considering the criteria of the Guide Textbook - PNLD 2011. Through the analysis of both materials, it was observed that it is much more possible to face activities of reproduction or repetition of algorithms than activities that involve challenging situations. In this research, the definition of 'Problem' is based on the idea of Echeverría. The author characterizes a Problem as a situation to be solved, for whom it does not have the immediate resources for the solution; but it is needed to articulate concepts and procedures. Therefore, the Problem Solving can be used as a tool to achieving the process of teaching / learning mathematical content, providing a link between concepts that are treated in different representations
