Social arithmetic, specifically the concept of discounts, is an important topic for junior high school students, yet learning outcomes remain consistently low. This research aims to develop "Discount Dash", a Scratch-based interactive learning medium, utilizing the MDLC development model (concept, design, material collection, assembly, testing, and distribution) user acceptance testing involving 13 pre-service mathematics teachers at a university in Bandung. The evaluation instrument consists of expert validation, questionnaires, interviews, and documentation, which includes visuals, programming, content, and usability. The results showed the media was very feasible, achieving a score of 95.7% from the expert validation, 97.7% from the open-ended questionnaire, and 96.5% from the closed-ended questionnaire, proving that "Discount Dash" has a feasibility and can be used as an alternative interactive learning medium to support the teaching of social arithmetic in junior high schools, increase student engagement, and help teachers present mathematical concepts that are relevant to daily life. Future recommendations include improving aesthetics with dynamic animations, expanding content to include profit and loss, taxes, and interest, and implementing tools in Class VII classrooms using quasi-experimental pretest-posttest designs to measure their empirical effectiveness.
