You can add more than one class to your Happy Numbers teacher account. To add a class, log into your teacher account, click on an existing class number at the top right corner and then click "Add another class". You will be redirected to a new class page where you can choose a grade level and enter your students names.

For Clever users: If you made the set up through Clever we are not able to make any changes in your class rosters (split classes / combine classes / transfer, add or delete students). For this purpose please contact your school Clever admin. Once your class info will be changed on Clever portal, it will automatically be synced with your Happy Numbers account.
