Click here if video is not present.
Once you have students added, if you do not have a LOGIN link to your Classroom on your site or menu...you can go to https://classrooms.teachertube.com/YOUR_USERNAME/login. Where "YOUR_USERNAME" is in the link, you will replace with your TeacherTube Username. Then your students can use the credentials you gave them to login.
In the same steps, you can also add Administrators and Parents. Please note, Parent accounts will only have viewing rights that you make available to the the public like a non-logged in user. They will not be able to post, view students courses/lessons/quizzes, grades, reports, not take courses/lessons/quizzes.
