This study aims to improve student activity and mathematics learning outcomes on the topic of properties of solid figures through the cooperative learning model type Make A Match. This study used classroom action research conducted in two cycles. Each cycle consisted of planning, action, observation, and reflection. The subjects were 14 fifth-grade students of SD Negeri 2 Kasihan, Ngadirojo District, Wonogiri Regency, in the 2024/2025 academic year. Data were collected through observation, formative tests, and documentation. The data were analyzed descriptively by comparing the results of the pre-cycle, cycle I, and cycle II. The results showed that student activity increased from 52.20 in the pre-cycle, to 64.40 in cycle I, and to 78.20 in cycle II. The average learning score increased from 64.79, to 72.00, and to 79.14. Classical mastery also increased from 35.71%, to 64.29%, and to 85.71%. The findings indicate that Make A Match encouraged students to pay attention, discuss, ask questions, solve problems, and present their work. Therefore, the cooperative learning model type Make A Match can improve student activity and mathematics learning outcomes in elementary school.
