This study aims to develop innovative creative games based on recycled materials as learning media that support teachers' understanding of sustainable education, particularly Sustainable Development Goal (SDG) 4 on Quality Education, at KB-TK Aisyiyah 25 Wage. The study employed a Research and Development (R&D) approach using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The analysis stage showed that most teachers had limited experience in utilizing recycled materials as educational play tools. The products developed included a number board, a smart syllable wheel, and three-language labels made from recycled materials. Field implementation showed that 95% of teachers considered the tools easy to use and engaging, while the children demonstrated high enthusiasm during learning activities. The final evaluation indicated an average 42% increase in teachers' understanding of sustainable learning media. These findings demonstrate that recycled-material-based games can provide effective and economical learning media while fostering teachers' awareness of environmentally responsible approaches in early childhood education.
