This study aims to determine the effect of the Make A Match learning model assisted by Wordwall media on the critical thinking skills of fifth-grade students in mathematics at SD Negeri 104217 Sidomulyo for the 2024/2025 academic year. The research method used is an experimental method with a quantitative research approach. To collect data, the instruments used were 5 essay test questions and a 30-item questionnaire. The sample consisted of 32 students, selected using total sampling technique. To assess students’ initial abilities, a pretest was conducted with an average score of 28, which falls into the "poor" category. The results showed an improvement in the posttest scores, with an average score of 83, classified as "very good." It can be concluded that the students’ learning outcomes improved significantly with the implementation of the Make A Match learning model assisted by Wordwall media. This was supported by the correlation coefficient test result of 0.764 ≥ 0.349, indicating a strong correlation. Furthermore, the hypothesis test yielded a t-count value of 6.492, while the t-table value was 1.694. Since 6.492 ≥ 1.694, the alternative hypothesis (Ha) is accepted and the null hypothesis (Ho) is rejected. Based on the t-test, it can be concluded that there is a significant positive effect of the Make A Match learning model assisted by Wordwall media (X) on students’ critical thinking skills (Y).
