## Preparing Elementary Preservice Teachers for Antiracist Mathematics Teaching

### Karisma Morton

I describe a unit on antiracist mathematics teaching I developed and implemented in an elementary mathematics methods course. It may serve as an example to other mathematics teacher educators on how to incorporate antiracist mathematics teaching in their courses. I report on the unit's components, its impact on the preservice teachers in my course, my reflections about the unit (including possible modifications), and implications for other mathematics teacher educators.
