If you want to share a OneDrive document with a specific group which already exists (such as the Elementary Staff), simply right click and select the share option on the respective document on OneDrive.com. Then, type the email address associated with that specific group. For example, Elementary Staff would be elementary@lakotaschools.org. Make sure to type a message in the "Add a message (optional)" field so that the individuals you are sharing a file with get an email notification.
