Based on the Historical-Cultural theory and on Vygotsky’s general propositions about the social nature of the human psyche and the concept of activity deepened by Leontiev, we have investigated elements of the learning of Mathematics teaching in Pedagogy students who participated in the Mathematics Club at a public university in São Paulo. The data analyzed were produced by the subjects in the form of individual reflective portfolio and collective final report. Data analysis reveals that the transformation of collective activities, triggered by the needs placed upon the subject, is linked to the movement of assigning new meanings to the reorganization of actions and their relation to the planning, the subject’s relation to the teaching of mathematics, the relationship between theory and practice in teaching organization, and objective conditions of the teacher’s work. Thus, it points to the movement of teacher training in teaching activity in the Mathematics Club.
