Improving the mathematical experiences of students depends on teachers' commitment and support for reflecting on and learning from their classroom teaching experience. In this article, the authors invite readers to consider using classroom photographs as tools for learning in a professional learning community (PLC) and perhaps as a stepping stone to forming teaching video clubs. The authors share three photograph activities that they have designed and used with various groups of educators to highlight especially powerful professional conversations focused on these photograph artifacts. Additionally the authors offer practical suggestions for selecting and using photographs to support collegial and professional conversations about what and how teachers may notice things in mathematical classrooms.
