Abstract
Contextualisation is expected to bridge school mathematics with real life, yet classroom contexts are often treated as universal, assuming that one context can fit all learners. Culturally Responsive Pedagogy (CRP) challenges this assumption by positioning students’ cultural and lived experiences as central resources. This paper examines how Indonesian primary teachers, engaged as learners in a culturally responsive mathematics professional development (PD) workshop on whole numbers and place value, came to reframe mathematical meaning as culturally situated rather than universal.
