Your account as a School Admin provides you all of the same rights as the teacher (and more).
Because the system requires a unique email for each user account, you cannot create a teacher account using the same email that is already used for your admin account.
However, you can add yourself as a teacher "entry" with the same email, without creating a separate teacher user account. Just skip clicking the checkbox for creating an account.
When we add/import students, we can associate applicable students with this teacher entry, and create a classroom space.
