This article seeks to show the importance of the Semiotics as field of analysis in the field of the Mathematical Education. In this way, we present excerpts of two researches carried out in programs of Post graduation in Education and Mathematical Education. In the perspective of the Semiotics, the research carried out by Miskulin, Moura & Silva (2003), approaches the study of the semiotics potentialities of the environment TelEduc in the concept’s representation. Mendes (2006), investigated the strategies utilized in the process of mathematical problems resolution, created by the structure, action and pedagogical mediation with the game computational Simcity 4.   Keywords: Semiotics Analyses. Mathematics Education. Computational Games. Explore- Investigative Activities. Education’s Software.
