This dissertation presents a proposal for a playful intervention, guided by the three-tier test, where an action plan will be developed based on the data collected. The objective of the study is to individualize as much as possible the difficulties identified through these data. The work begins with a brief historical context about the evaluation, also presenting the concept of the three-tier test in general. Then, the three-tier test is applied to the combinatorial analysis content, the data is collected and, with this data in hand, an action plan for the intervention with the students is developed. After the intervention, the students take a new three-tier test so that the developments can be analyzed
