While there is widespread agreement that "all" learners of the 21st century need to be numerate and literate, reforming pedagogical practices to achieve such an outcome is challenging for many teachers. This is a report of one aspect of a project which aims to integrate a culturally responsive pedagogical mathematics practice within communities of mathematical inquiry. The focus of this report is on the exploration of dynamic mentoring from the perspective of teachers. The results demonstrate how "in the moment" actions from mentors during lessons cause reflective transformations in pedagogical practices.
