Attendance is very vital to online learning. Your child should remember that school is still important, and they need to check their schoolwork daily!
Most of my class is synchronous- meaning they attend live daily meetings and complete work done in class while in the meetings.
If you are asynchronous- your child should be responsible enough to check daily agendas in EACH TEAM, watch class recordings, and complete assignments in teams and on the agendas.
I can see when your child logs in to TEAMS and everything they do while there. If your child does not log in, or does not complete work/watch recordings, they will be marked absent for that day!
