Although considerable literature illustrates how students' experiences and identities are racialized in mathematics education, little attention has been given to Asian American students. Employing ethnographic methods, this study followed 10 immigrant Chinese-heritage families to explore how the racial narrative of the model minority myth was locally produced in mathematics education. We draw on constructs of racial narratives and cultural production to identify the local production of the narrative "Asians are smart and good at math" during K-12 schooling. Specifically, the Asian American students (re)produced racial narratives related to three cultural resources: (a) Their immigrant parents' narratives about the U.S. elementary school mathematics curriculum; (b) the school mathematics student tracking system; and (c) students' locally generated racial narratives about what being Asian means.
