PENGEMBANGAN MEDIA GAME EDUKASI ADVENTURE COUNTING BOX MELALUI PEMBELAJARAN BERDIFERENSIASI PADA MATERI PENJUMLAHAN DAN PENGURANGAN KELAS 2 SEKOLAH DASAR

The process of learning mathematics in elementary schools often faces challenges, such as students' lack of interest and limited interactive learning media. One possible solution is the use of concrete learning media based on educational games in differentiated learning. This study aims to develop and implement the Educational Game Media Adventure Counting Box in addition and subtraction material for second-grade elementary school students to enhance their understanding and learning motivation.
The research method used is research and development (R&D) with the ADDIE model, consisting of five stages: analysis, design, development, implementation, and evaluation. The results indicate that the developed media has undergone expert validation with a high feasibility level and received positive responses from teachers and students. The implementation of this media at MI Gamping Trenggalek showed an improvement in students' understanding of addition and subtraction concepts for whole numbers up to 20, with an average student score of 90 and higher active engagement compared to the lecture method. Student responses to this media reached 95.5%, indicating that it is engaging and enhances learning motivation. Additionally, teacher responses reached 100%, demonstrating that the media aligns with the curriculum and is easy to implement in teaching. Thus, it can be concluded that the Educational Game Media Adventure Counting Box is effective in improving students' mathematical understanding and supporting the implementation of differentiated learning in elementary schools.
