Columns in the Gradebook are only created by adding an assignment in Canvas. If you need to create a column in the Gradebook to use for manual grading, you can create a No Submission or On Paper assignment.
No Submission assignments are when you do not want students to submit an assignment in Canvas. This assignment type can be used to create extra columns in the Gradebook, create an assignment that involves multiple scores, or give extra credit.
On Paper assignments are when you want students to submit an assignment to you but not through Canvas. This assignment type applies to traditional face-to-face courses or hybrid courses when you want the assignment turned in during class, but you still want to create a column in the Canvas Gradebook for grading purposes. When student view the assignment, they see a Submitting: on paper notice.
To create multiple columns at once, you can upload changes to the Gradebook.
Note: The Gradebook only shows published, graded assignments, so Not Graded assignment types will not appear.
