I've published an Online Rubric spreadsheet add-on that will allow you to grade and send rubrics to students via email. You can install it from the add-on store or use the link below.Uses:
If you're creating an assignment within Google Docs, you're probably better off using +Andrew Stillman
's Doctopus (from which this script borrows some code).However,
other assignments that aren't attached to one specific document or at all (like presentations or ongoing monthly projects), this rubric gives you a simple way to provide feedback and keep a record of it for yourself.
It's my first add-on, so let me know if you have any questions, problems, or suggestions.
And of course, I'd love positive reviews
:) If any issues exist that would keep you from giving you one, let me know so I can rectify it.
