This study aimed to describe the implementation of a mathematics e-module based on the Wordwall application through an Interactive Smart Board and evaluate its effectiveness in improving the learning outcomes of fifth-grade students at SDN 233 Mattampawalie. This research employed a quantitative approach with a pre-experimental design using the One-Group Pretest–Posttest Design. The sample consisted of 24 fifth-grade students selected through total sampling. Research instruments included pretest and posttest assessments, observation sheets to evaluate learning implementation, and documentation. Data were analyzed using descriptive statistics and inferential techniques, including the Shapiro–Wilk normality test, Wilcoxon Signed Rank Test, and N-Gain analysis. The results indicated that the mathematics e-module was implemented successfully according to the planned learning procedures. The students’ mean score increased from 67.58 in the pretest to 80.67 in the posttest, showing an improvement of 13.09 points. The percentage of students achieving learning mastery also increased from 20.83% to 79.17%. The Wilcoxon Signed Rank Test produced a significance value of 0.000, below the 0.05 threshold, indicating a statistically significant difference between pretest and posttest results. Additionally, the average N-Gain score was 0.367, categorized as moderate. These findings suggest that integrating the Wordwall-based mathematics e-module with an Interactive Smart Board is effective in improving fifth-grade students’ mathematics learning outcomes at SDN 233 Mattampawalie.
