The aim of this study was to establish the correlation between cooperative learning and the representational dimension of quantitative reasoning in university students. The study is based on a quantitative research approach, a correlational level and a non-experimental cross-sectional design. The sample consisted of 121 students from a private university in Lima. To evaluate cooperative learning, a questionnaire composed of 29 questions was used. On the other hand, to evaluate the representation dimension of quantitative reasoning, an evaluation was carried out through a real context situation using a rubric. The results indicated a significance level of 0.000, which led to the conclusion that there is a significant relationship between cooperative learning and the representation dimension of quantitative reasoning.
