This research work aims to build a praxeological organization of proportionality from an epistemological and ecological study, in order to determine, describe and characterize the presence of proportionality at the primary level. This objective starts from the question: What is the mathematical organization of the unit, which contains the theme of proportionality, in the official mathematics workbooks at the elementary level? To answer this question, we developed a qualitative research with a bibliographic approach, taking as a theoretical and methodological reference the Anthropological Theory of the Didactic, which uses praxeologies as the unit of analysis. We began by reviewing the official curricular documents and we identified the presence of our object of study from the third year of primary school in the competence related to solving problems of regularity, equivalence and change. Then, with the theoretical aspects provided by the framework, the workbooks were analyzed and 3 types of tasks, 13 tasks, 13 techniques and technological discourses that justify our Mathematical Organization were identified. The type of task related to Finding the unknown term in a situation of proportionality is privileged, the tasks are presented under the assumption of being proportional and it is assumed that the concept of magnitude is known. Furthermore, in most of the tasks the use of the proportionality table as ostensive is explicit and in these small arrows or lines that suggest the treatment of the technique from a perspective of internal or external relationships. In turn, these relationships have allowed us to describe two implicit concepts of proportionality. Finally, identifying the praxeologies in the four analyzed workbooks has allowed us to have a greater scope to conclude that the sequential development of the tasks must present a link between their respective techniques. In this regard, at the end of the research, a mathematical organization related to a sequence on the presentation of tasks is proposed for our object of study at the primary level.
