I’m a math educator at the Math Forum @ Drexel University.  “Math educator” is a purposefully open-ended label.  I write problems and supporting materials for our Problems of the Week, observe, mentor, coach, and develop PD for teachers in grades K-12, teach Problem Solving in Geometry and Measurement in Grades 3-8 as part of the Math Forum’s online PD program and two electives in Drexel’s Mathematics Learning and Teaching Master’s program (Teaching Math with the Geometer’s Sketchpad and Learning and Teaching Calculus with the Geometer’s Sketchpad, both of which are also available as Math Forum online PD), occasionally tweet as @MFAnnie, speak at conferences and workshops, and ride my bicycle to work as often as I can.
