I haven’t gotten any calls for my kindergartener just messages on seesaw. But I have been waking her up and having her do her work at 9 am everyday. I think they are calling because you aren’t having them log on at 9am. I would just get everyone up at 9 and have them log on and do their best. You obviously can’t do work with three kids in different grades all at the same time. I don’t think the work has to be perfect, as long as they are logged in and trying to do the work, they will stop calling you. Your third and fourth graders should be able to do the work on their own and if they can’t then the teacher should give them something easier. You definitely shouldn’t be doing any of the work for them. I do help my kindergartener but the work is usually only an hour or an hour and a half. We are usually done by 10:30.
