Abstract: This study evaluates the effectiveness of applying the Teaching at the Right Level (TaRL) model to address learning difficulties related to the convergence of numerical sequences. Analysis of students’ written test on the concept of sequence convergence revealed students had a significant reduction in errors between the two cycles, implying that students not only improved their understanding but also learned to correct their mistakes. Recommendations to expand the implementation of TaRL were given based on these promising outcomes. By scaling up this approach, more students may overcome specific challenges in this domain, further enhancing their academic success.

Abstract: This article addresses the learning difficulties of sequence limits with second-year high school students in Morocco. This occurs after students have been taught about different types of numerical sequences across various educational levels.
