Well Jeff, as a long time sys-admin I will tell you that they should be tought the "standard" way.  That is to get logged into root and add the user to the appropriate group listing in the /etc/group file.  Although you can do pretty much the same thing with other tools such as usermod and groups these tools don't always exist on every installation. :-)
