In this article the authors analyze three episodes from an elementary mathematics teacher education class: two where students were positioned as children learning mathematics and a more extended one where students were positioned as teachers. The instructors presented the figured world of reform pedagogy in at least two ways over the course of the semester: by describing it and approximating it in class activities. The authors propose that by recognizing certain models of identity for children learning math, students in Mathematics for Elementary Teachers drew on corresponding models of identity for elementary mathematics teachers.
