What alternative method can teachers use to add students to their Classroom class if email invitations are unavailable?

Sharing a unique class code is an effective alternative method for adding students to a Google Classroom class when email invitations are not an option. Each Google Classroom class is assigned a unique code that teachers can display or share with their students. By entering this code, students can join the class directly without needing an email invitation. This method promotes ease of access, as students can join from any device with internet connectivity, and it eliminates reliance on specific email services or personal accounts. It fosters a more inclusive and straightforward method for student enrollment, catering to various circumstances where email communication might be restricted or unavailable.
