This project explores how culturally responsive pedagogy influences the mathematical disposition and achievement outcomes of diverse learners (Māori and Pāsifika nations students) in high poverty areas in urban Auckland. We investigate how attending to culture, language, and identity affects the construction of mathematical dispositions and how the elements of ambitious or inquiry teaching support students developing rich mathematical understandings. Using classroom data we examine the role of mentors working with teachers to co-construct mathematical inquiry communities and explore how this is achieved in culturally responsive ways.
