<![CDATA[Purpose: this study aims to analyze the effectiveness of the jarimatika "fingermath" method in improving multiplication skills and learning interest in mathematics among third-grade elementary school students. Method: this research employed a quantitative, quasi-experimental, one-group pretest–posttest design. The participants consisted of 17 third-grade students. Data were collected through pretest and posttest assessments of multiplication skills and analyzed using descriptive statistics, a paired-samples t-test, and effect size (Cohen's d). Findings: show that the jarimatika method can improve multiplication calculation skills and foster interest and engagement in learning mathematics among third-grade elementary school students. However, the increase in learning outcomes is not yet statistically significant. Implications: this research theoretically strengthens mathematics learning through a concrete approach, while also practically demonstrating that the jarimatika method can increase student activity, interest, and understanding, and can serve as a basis for developing innovative learning media. Originality: lies in the application of the jarimatika method, which simultaneously examines the improvement of multiplication calculation skills and the learning interest of third-grade students in madrasah ibtidaiyah, with a concrete learning approach that is in accordance with the characteristics of the Merdeka Curriculum. ]]>
