How do I add a student to an existing assignment?
For group assignments, you can add the new student to existing groups by clicking Edit Group

For individual assignments, you can add new students with these steps:
- Open the assignment to see the teacher dashboard
- Click More Actions
- Click Versions Assigned
- Click the Assign arrow next to the new student name at the bottom of the list

The student should now have the individual assignment sent to them as well.
