Our students come to us 1 night per week for 45 minute classes. For example, Monday at 4:30 is 4th grade Math, but there might also be a Tuesday at 5:45 4th grade math. Should we set up a team for each class time or a team for each grade/subject with a channel for each class time? We are unsure how to best prevent students from joining the wrong class time since a private channel can not have a recurring meeting.
