This video will show you how to grade student work within Canvas. 

To grade a student's assignment within Canvas you simply need to go into the course and click on assignments. Click on the assignment you would like to grade and on the right hand side you'll see speed grader. If you click on speed grader this student's work will populate. I can flip through and look at each student's submissions by clicking on the arrow in the top right corner and the assignment will pop up right here. And the left hand side of the screen as you can see this assignment just says this is an example of student work. I can assign the students a grade by putting a number in this box. I can leave this student a comment. I can attach a file if there's something I'd like for a student to see. I can add a video. I can record a video or I can click on upload media to upload a video I've already created. I can leave a student audio notes by clicking speech recognition when I'm finished I'll click Submit and when the student logs in they can see the feedback that I left for them.
