Participant observation, semi-structured interviews and document analysis were used as research techniques (Marconi; Lakatos, 2021). In data analysis, the principles of triangulation were followed (Stake, 2011). The theoretical basis is based on the ideas of Vergnaud (1986; 2014). The results indicate that, from the perspective of Conceptual Field Theory, the construction of concepts occurs through conceptual fields and the situations proposed by the teacher in the classroom play a fundamental role in this process. These situations must be diversified to open space for conceptualization that interrelates the different ways of representing a rational number, which requires understanding the nature of this type of number and not just the appropriation of the definition
