In the spirit of reducing paper try this tip to "force the user" to make a copy versus writing over the original. Simply change the last part of the URL.
Force the user to make a copy:
If you are navigating the students to a template or a Google Doc that you want them to put on their own Drive and you wish for them to copy, all you have to do is edit the URL! Remove the phrase /edit at the end of a Google Apps URL and change it to /copy.
