To view the .notebook files, you need the SMART Notebook software. You can download a free trial version here.
To view the .key files, you need the Apple Keynote program. If you don't have that, the same slides, almost exactly, can be found in various PDFs. See "Nothing Works" on this page. See these files also: Reimagining | Manipulatives | Calculator | Computer.
If you really need me to make PDFs of these, I can. However it won't be soon, as I'm starting another workshop next week.
