<![CDATA[This research aims to develop interactive Math Fraction multimedia on the material of adding and subtracting fractions for fourth-grade students at Bulusari 3 Elementary School. The mathematics learning problems at this school include low student achievement and a lack of variety in learning media, which impacts students' low interest and active participation. This research uses the Research and Development (R&D) method with the ADDIE development model, which consists of five stages: analysis, design, development, implementation, and evaluation. The limited trial involved 5 students, while the large-scale trial involved 18 students. The instruments used include a validation sheet, a practicality questionnaire, and an effectiveness test. The validation results showed scores of 92% from content experts and 98% from media experts, indicating that the media is highly valid. Practicality tests by teachers and students showed an average score of 93.2% (very practical). The post-media effectiveness test showed that 100% of students achieved the Minimum Mastery Criteria (KKM). These results indicate that the interactive multimedia Math Fraction is suitable for use as a valid, practical, and effective learning medium.]]>
