I just made these Prodigy login cards for my students. I have found that the login cards that the website provides are either too large (one page) or a small strip. These can be printed out or filled in using the editable version. When printing the editable version, be sure to print two slides per page. If you wish to make the cards smaller, you can insert duplicate slides and print as many as four or six per page.
I always change my student's password to their first name to make logging in easier. If you need help doing this, email me at email@example.com
