Welcome to Reflections, NCTM's video-based professional Web site designed to help teachers - individually and collectively - examine their teaching of mathematics. By integrating lesson videos, pre- and post-lesson discussions, student work, and reflective talks and analyses, Reflections serve as a tool to systematically observe, analyze, critique, and reflect on our classroom practices.
