How do I set empty cells to zero for a single grade item?
Note: Gradebook does not include ungraded items in the course grade calculation. Empty cells could result in a higher course grade average for a student. To include a gradebook item in the course grade calculation, you must enter a grade of zero or higher.
Go to Gradebook.

Find the grade item for which you want to assign zeros for missed work. Select the dropdown arrow in the grade item's column header.

Select Set Score for Empty Cells.

Enter the grade you will assign for empty cells.

Click Continue.
