If you are using temporary teams, students are prompted to join a team for each Team-Based session. You can tell them the team names and which team each of them should join, or you can let students form their own teams and create the team names. Students who enter the same team name are assumed to be on the same team.
As students arrive in class and begin to join teams, progress of team formation appears in your instructor view.
When students have joined teams, you can start the Individual Round so they can begin answering questions.
