Abstract: In this report, we present an advance of doctoral research. We explore teaching alternatives that promote proportional reasoning in Mexican students between 14 and 15 years old with the support of digital technology. We designed a sequence of activities that pretends to signify the concepts of ratio and proportion in their diverse representations and from the perspective of linear functions. For the design of the tasks, elements of the Realistic Mathematics Education framework and Cuevas-Pluvinage Didactics were used. The learning objectives and proposed activities were organized through a hypothetical learning trajectory. Subject to presenting the group results, we randomly selected a student to present the analysis of the results achieved. We found that the tasks promoted proportional reasoning.
