This document discusses the standards for mathematical practice and how teachers can develop these practices in students. It begins by posing questions about what math is and what it means to do math. It then outlines the session which will explore how math tasks can develop students' understanding of what mathematicians do if set up and implemented properly. It describes the standards for mathematical practice and provides an example penny jar task that fourth graders worked on, noting the teacher's moves to support the practices. It closes by reflecting on ensuring all students regularly engage in tasks promoting the practices and how teacher educators can better equip teachers to implement the standards.
