Arithmetic Slide Shows An Innovative Way to Better Understand Arithmetic Producing animated Powerpoints is a time consuming task; therefore it will take time to make our entire arithmetic course available in this format.  Herb has graciously given us permission to post unedited first drafts of his scripts that will be used as the basis of the Powerpoint presentations.  Click on links below to view slide shows.   * To optimize viewing slide shows, see note below table.
