This study aimed to develop digital educational game-based teaching materials for teaching multiplication to third-grade elementary school students that are valid, practical, and effective. The study employed a Research and Development (R&D) method using the 4D development model, consisting of the stages of Define, Design, Development, and Dissemination. The results showed that the developed teaching materials achieved a validity score of 91.9%, categorized as highly valid, based on assessments by media, language, and material validators. The practicality level based on student responses reached 67.91, categorized as practical. The effectiveness test through pretest and posttest results showed an N-Gain score of 84%, categorized as effective. Based on these findings, the developed digital educational game-based teaching materials for multiplication were considered suitable for use in the learning process of third-grade elementary school students. The integration of educational games into teaching materials provides an engaging alternative that can support students’ understanding of multiplication concepts while creating a more interactive learning experience. Therefore, these teaching materials can be used as an innovative learning resource to support mathematics instruction in elementary education.
