Mathematics education in the 21st century requires the integration of technology and interdisciplinary approaches to meet students’ diverse learning needs. However, conventional teaching materials often fail to engage students actively or connect mathematical concepts to real-world contexts. This research aims to develop interactive teaching materials based on the Science, Technology, Religion, Engineering, Arts, and Mathematics (STREAM) framework for the topic of ratio by utilizing the Lumio platform to enhance the learning experience. This research employed the ADDIE development model consisting of Analyze, Design, Develop, Implement, and Evaluate stages. The study involved 3 expert validators, 1 mathematics teacher, and 42 Grade VII students, including 10 students in the small-scale trial and 32 students in the large-scale trial. The instruments used in this study included expert validation sheets, practicality questionnaires, and systematic thinking skill tests. At the same time, the data were analyzed using percentage techniques based on validity, practicality, and effectiveness criteria. The results showed that the developed teaching materials achieved validity scores of 85%, 84%, and 92%, categorized as “very valid.” The practicality results reached 82% from students and 86% from the teacher in the small-scale trial, while the large-scale trial obtained a score of 80%, categorized as “practical” to “very practical.” Furthermore, the effectiveness test showed an increase in student learning outcomes, resulting in an effectiveness percentage of 73%, categorized as “effective.” These findings indicate that the STREAM-based teaching materials assisted by Lumio are valid, practical, and effective for teaching ratio topics.
