In this paper we produce a qualitative analysis of the strategies of students in a class of the 5th year of Elementary School to solve a modeling problem. With this intention, we base ourselves on Mathematical Modeling understood as a pedagogical alternative and on Peirce’s semiotics that makes it possible to infer about the production and use of signs to refer to an object. The data that supported our analyzes are the written reports and transcriptions of audios and videos produced in the development of a modeling activity that had as its theme the distance traveled from home to school using a bike. Starting from a real situation, the students established strategies to arrive at a solution to a modeling problem in which gesticulated, spoken and written signs were articulated with the objects related to the problem, the hypotheses and the mathematics used under questioning and guidance from the teacher.
