This research was motivated by the low cognitive ability of students in learning mathematics in multiplication. The purpose of this study was to develop a learning medium called “Fun Multiplication with Snakes and Ladders and Multiplication Cards” (PADUKA) and to test its feasibility, practicality, and effectiveness in improving the cognitive ability of fourth-grade elementary school students. This study used the Research and Development (R (2) PADUKA media is practically used in learning based on positive responses from teachers and students; (3) PADUKA media is effective in improving students' cognitive abilities with an N-Gain value of 0.65 (moderate category) and an effectiveness value of 91.1% (very high category). The paired t-test shows a significant difference between the pretest and posttest scores (p=0.000), and the independent samples t-test shows a significant difference between the experimental and control classes (p=0.005). Based on these results, it is recommended that PADUKA media be implemented more widely in mathematics learning in elementary schools.
