Class codes are used when students create their own accounts and need to sign up for their teacher's class rather than the teacher creating the class and the student accounts for their students. The Virtual Classroom Tutorial covers the difference between these options near the end of the video.
Students can join a teacher's class through the following:
- Go to "My iCivics"
- Click the "Classes" Tab
- Select "Join A Class" on the right
- Type in the class code given when the class was created (located on the teacher's account under Classes > Class Code in white on the dashboard)
