this new video I demonstrate how to add a co-teacher to Google Classroom, how that co-teacher accepts the invitation, and how you can remove a co-teacher from Google Classroom.
The important take-aways from this video are:
1. A co-teacher can only be added if he/she has an email account in the same G Suite domain as you.
2. A co-teacher can do everything you can except delete/ archive the classroom.
3. You can remove a co-teacher from the classroom.
