This study aims to implement the Teaching at the Right Level (TaRL) approach to improve student learning outcomes in Mathematics, specifically on division operations, in class IV A of SD Negeri 47 Palembang. The research method used is Classroom Action Research (CAR), conducted in two cycles. Each cycle consists of planning, implementation, observation, and reflection stages. The results show a significant improvement in students' learning outcomes. In the pre-cycle phase, 62.5% of students had not achieved the Minimum Mastery Criteria (KKM). After implementing TaRL in the first cycle, the number of students who had not met the criteria decreased to 47%, and further dropped to 16% in the second cycle. Meanwhile, the percentage of students meeting the KKM increased from 37.5% in the pre-cycle to 53% in the first cycle and 84% in the second cycle. The implementation of the TaRL approach proved to be effective in enhancing students' understanding and learning outcomes, especially in mastering division operations.
