 I'm going to show you how to share a document that you've created and is already in your drive. If you're working on the document, all you need to do is go to the top right hand corner to the blue share button, click on it, dialog box will pop up. Right now if you want to share this with an individual person or other teacher down at the bottom where it says add people, all you need to do is type in their email address and either give them rights to edit, they can comment on it or view. You can also share this document with a web link. Right now by default it's always private, only the people listed below can have access. If you click the change button, go to anyone with the link, can edit, click save, then click share and save and you are all done. All those people now have access to it, the person, the individual you invited, as well as anybody with this link. All you have to do now is copy that link, click done, and email or do a tiny URL to shorten that link and pass it up to the people that need it and they will have access to that document.
