We sent out a survey. Only one of our gymnast had a set time that she had to be online. All of the others just had to get on at some point during the day. That makes it much easier to schedule workouts.Around us, many of the schools have a morning zoom or Microsoft teams meeting for 30 to 90 min and the rest of the day is at their own pace and schedule. For us with a 2nd and 4th grader ( with 3 year old little brother) we do school from 8-10:30 and 12:30 until 2 or 3. Some of the high schools are the same way.
