I assign short educational videos to watch.

These are now in-lieu of 'in-class participation points', so i'd like to assign automatically points to everyone who watches the videos. How do I do that when I set up the assignment?

I have points assigned

I have no submission

I have no rubric (just watching it seems fine).

It shows up in tehgradebook as an assignment but when student watch the videos, the grade remains unallocated? 

Thanks for the advice.
