The article focuses on the transformations that teachers imprint on didactic situations of mathematics associated with a socio-constructivist didactic approach. The case of two educators working with the subject of Information Processing in preschool is studied. Methodologically, we consider this study a Didactic Development Engineering (Perrin-Glorian, 2011). The analysis was carried out from a double theoretical perspective: the didactic situations are characterized and analyzed from the Theory of Didactic Situations (Brousseau, 1998), while, for the analysis of teaching practices, the double didactic/ergonomic approach was mainly considered. (Rogalski and Robert, 2001) and the ethnographic perspective (Rockwell and Mercado, 2003). Although the transformations identified are different from each other, in both cases the essence of the didactic purposes was preserved. This is expressive of the need and feasibility of appropriation processes. The main contribution of the text is the identification of factors that underlie these transformations, the needs to which they respond and the tensions they create in decision-making in the classroom.
