These modules are designed to support preservice secondary mathematics teachers’ development of pedagogical skills related to professional noticing of student thinking and leading productive mathematics discussions in technology-mediated geometry environments. The modules engage teacher candidates in dynamic geometry tasks and provide opportunities to analyze videos and samples of student work on the same tasks. Throughout the sequence, attention is given to the coordination of students’ interactions with technology and their expressed geometric reasoning. Tasks are intentionally designed to deepen understanding of foundational geometric ideas while simultaneously building technological pedagogical geometry knowledge.
