Meeting the challenges and competition in 21st-century education involves the cultivation of learners capable of navigating an increasingly globalized world. This necessitates the development of critical, independent, and disciplined thinking skills. Contemporary education goes beyond enhancing cognitive, attitudinal, and psychomotor abilities; it centers on learning frameworks encompassing Critical Thinking and Problem Solving, Communication, Creativity, and Collaboration Skills. Toraja culture has gained global recognition through its distinct elements such as ma’parapa, ma’kombongan kalua’, mantaa, and didosa. This research seeks to explore how school culture can be integrated to address the challenges of 21st-century mathematics education. The study, conducted qualitatively, employed interviews and open questionnaires for data collection. The findings reveal that Toraja culture, particularly ma’parapa, ma’kombongan kalua’, mantaa, and didosa, embodies cultural values encompassing moral, practical social, educational, and belief values. These values can be seamlessly integrated into classroom mathematics instruction to address the demands of 21st-century mathematics learning, particularly in terms of fostering critical, independent, and disciplined thinking.
