From any page in your portal, click the Settings link near the top of the page and then look for the Gradebook Settings area on the next page. Click the link for the gradebook you wish to configure to open the settings page for that gradebook. On this next page, you will see the options for "Rounding" and "Default Score" in the left column. You will only see "Averaging" if an administrator has enabled this feature. Click the Go button next to the setting you wish to change.
The Rounding option allows teachers to change how many decimal places will be displayed for overall grades. This number can be set to either 0, 1, or 2 using the drop menu. If zero is selected, the gradebook will round to the nearest whole number. For example, if a student's overall grade is 93.667%, the gradebook will round this score to 94%.
Note that this setting only affects the student's overall grade, not individual grades entered for assignments. Even if your rounding is set to 0 decimal places, you can still give a student fractional points on any assignment and the gradebook will not round this score. This allows for a more precise rounding of the overall grade.
By default, new assignments in your gradebook will not have any value entered as a score, just empty cells. The Default Score option allows teachers to have all students start new assignments with a score of zero points instead.
If the Default Score is set to "0 (Zero)," the zero will immediately count towards the student's overall score in your gradebook. For this reason, most teachers choose to stick with the default setting of "Empty".
Note: Because a 0 (zero) is technically a counted value in the gradebook, you cannot use autofill to overwrite cells with a zero in them. If you use autofill prominently, you will probably want to leave this option set to "Empty."
