I have gathered pdf files of some PowerPoint presentations I have made at conferences because these summarize visually ideas I think are important. Many of these presentations are about math domains, and you can find out more about these domains in the Publications and in the Teaching Progressions for those domains. Sort the Publications list to find papers for that math topic, and look at the column following each Visual Presentation title to see which Teaching Progression to view for more detail and audio to go with the visual.
