This study aims to understand how the use of the game congklak can contribute to improving the numeracy skills of grade II elementary school students. Using a qualitative approach through a case study, this research involved students, teachers, and parents as resource persons to gain in-depth insights into the role of games in the math learning process. The research subjects were grade II students at SDS Islam Ulul Albab. The findings show that congklak can be an effective tool in helping students hone their numeracy skills. In addition to offering a fun way to learn, this game also helps train social skills, critical thinking, and strategy application. Based on observations and interviews, students were more active and enthusiastic when learning math through congklak, and were able to relate the subject matter to everyday life situations. Overall, congklak proved to be not only an interesting learning medium, but also has an important role in supporting students' cognitive and social development, so it has the potential to be an effective learning innovation at the primary school level.

Realistic Mathematics Education (RME) is an effective approach to improve mathematics learning outcomes while providing students with opportunities to gain real experience in understanding mathematical concepts. Data analysis used by comparing two cycles obtained from student learning evaluation results. The results of the study illustrate that there was a significant increase after using a realistic approach. This study aims to improve the understanding of the concept of distance between points in MA AISYIYAH PALEMBANG students using a realistic approach. This method uses the Class Level Approach (CAR) research method which is carried out in two cycles. Data were collected through conceptual understanding, observation, and documentation.
