This activity is geared for the teacher that has the TI-Navigator System, a Smartboard, and possibly TI-Smartview. Even if you only have a projector (and no smartboard), you can use the PDF file. This activity is one that I use the first two or three times that your class uses the TI-Navigator System. The Adobe document included has screenshots and captures of specific keystrokes to visually assist students in the logon process.
