. An educational experiment is presented in which the design of a set of didactic activities is tested under the structure of guided exploration, which allows the student to adopt greater responsibility at the moment of developing them. The use of material artifacts (sheet of paper and graduated ruler) is promoted for the mathematical work of first year university students. The notion of variation of variables, dependence relationship between variables, the different semiotic representations of these relationships and the concretion of a possible functional relationship are studied through a ludic activity related to the trajectory of an ant through the perimeter of a square. The results indicate that the integration of material artifacts and the promotion of a work on different semiotic representations of the mathematical object, allows students to exercise an inspection of it and an advance in their notions about the concepts in question. In addition, this type of ludic activity facilitates the approach to mathematical concepts in university students, thus allowing access to the possible generation of hypotheses and their verification favored by the integration of technology.
