Notebook: Arithmetic K-8

  • edit - This is meant for teachers and course developers. If you have Adobe Captivate, you can get our raw lesson files and customize them for your own students.
  • wbd - slide files for the Blackboard Collaborate classroom. This one is our lowest priority, but if we hear from many people that they need it, we can move it up on the schedule. Contact teacher.tammy.moore@gmail.com to let us know.
  • zip - Important: create a folder and add only one zip to it. Unzip it. The multiscreen file is the one you want to double-click to launch the lesson from your own computer or server. We update these frequently, so check back periodically for a refreshed copy of the zip and replace old files. Refreshed copies not only have any corrections needed but they also have new code to keep up with the rapid changes in devices, browsers, and HTML5.
