<![CDATA[This study aimed to develop and analyze the practicality of a Local Culture-Based Mathematics Teaching Module rooted in Batak Angkola culture (MOAMABUL) on the topic of Systems of Linear Equations in Two Variables (SLETV) to support students’ creative thinking skills. The study employed a Research and Development (R&D) approach using the 4D development model, consisting of the define, design, develop, and disseminate stages. The participants were students of class X TAV-1 at SMK Negeri 2 Padangsidimpuan who were involved in the product trial. Data were collected through a student response questionnaire administered after the implementation of the developed module. The data were analyzed quantitatively using descriptive statistics by calculating the percentage scores of students’ responses to determine the practicality level of the product. The results revealed that MOAMABUL achieved an average practicality score of 66%, which falls into the “fairly practical” category. These findings indicate that the developed module is feasible for use in mathematics learning and is positively received by students. The integration of Batak Angkola local culture into the learning materials enables students to understand mathematical concepts in a more contextual and meaningful manner. Therefore, MOAMABUL contributes as an alternative teaching resource that incorporates local cultural values into mathematics education and has the potential to support the development of students’ creative thinking skills.]]>
