A CodeMonkey subscription can only be connected to one teacher account. Once classrooms are created, the teacher is able to add your colleagues as a co-teacher.
The co-teacher is able to add students to the classroom, see their progress, assign courses to the classroom and so on (all the abilities that you would have over the classroom).
Once you add her as a co-teacher to a classroom, the classrooms will show in their CodeMonkey account.
