This research aimed to develop a media uno stacko mathematics based on a realistic mathematical approach to improve students’ understanding of mathematical concepts. The development model used was ADDIE with the pretest and posttest research designs in the control and experimental classes. The instruments used in this study were documentation, tests, and questionnaires. The analysis showed that students have problems in understanding the concepts and need engaging learning media. Then we think to design a media uno stacko mathematics. After that, media and learning tools that have been made subsequently validated by media experts, material experts, and learning design experts, each of whom with an average validation result in the very high category. In its implementation in the field shows that this media is effectively used for learning by obtaining an average N-Gain in the experimental higher than the control class with a significant difference. Furthermore, the practicality questionnaire showed that the media unomat based on a realistic approach to practical mathematics was used to obtain very good results. Based on data obtained, it was concluded that the uno stacko mathematics media was valid, effective, and practical.
