Are there specific times when students need to log on?
K-5 does have specific 1 hour meeting times.
6-12 does not.
All students must stay on pace, which means working every day to complete the assignments that are due each day. If a day is missed, students can make it up on another day or over the weekend. On Monday's I take attendance for the previous week by checking to make sure all assignments were completed the week before.
