A student may sign in to the Edmodo website using a user name and password that he creates, along with a Group Code supplied by a teacher. The Group Code enables the student to access specific class information and interact with that class and teacher.
Once a teacher initiates a class group on Edmodo, the teacher then provides the class with the Group Code so that they can join the class group online. Once a student receives the Group Code from a teacher, the student can sign in. Students can join multiple class groups, depending on the number of classes they have that use Edmodo.
