Once you have added Grading Periods to a course, you can filter the gradebook by grading periods using the drop down filter. By default, you will see all grading periods as shown in the image below.
To filter by a specific period, use the Dropdown menu to choose the Grading Period you’d like to view.
You will see only those grades and the total grade for that period.
