How can I find assignments which have not yet been graded?

To find ungraded submissions for a particular assignment:

1. Click on the assignment.
2. Then click on view submitted assignment link in the top right of the page.
3. A table that includes a  Grade column is displayed. Sort the table row by clicking on the column title, in this case "Grade". Assignment submissions will then be ordered according to their given grade, with ungraded submissions displayed at the top of the column.
