Abstract


This research aims to describe (a) the landscape of Least Common Multiple (LCM) learning for fostering creative thinking, (b) the design of the developed number tree media used in LCM learning, and (c) the effectiveness of the number tree media employed in LCM learning in the fourth-grade class at SDN 1 Pucanglaban, Tulungagung Regency, as a stimulus for students' critical thinking. The study follows a Research and Development (R&D) design based on the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Data collection includes numerical and textual information gathered from teachers, students, media experts, and subject matter experts through interviews, product assessment questionnaires, and pretest and posttest results. The results are: (1) the learning resources used in the sixth-grade class at SDN 1 Pucanglaban, Tulungagung, consist of curriculum-aligned textbooks for 2013. However, alternative learning media that could facilitate more active, creative, and critical student engagement have not been employed; (2) the "Number Tree" learning media developed using the ADDIE model is deemed highly suitable for Mathematics instruction, specifically in the context of LCM; and (3) the development of the Number Tree, grounded in fostering creative thinking, has proven effective in enhancing Mathematics learning among fourth-grade students at SDN 1 Pucanglaban, Tulungagung, during the academic year 2022/2023.
