Well... as I emailed 3 of my 8th grade son's teachers last night, so far I'm failing miserably at the schooling at home... but keep in mind that I'm still working full time and still having make all the meals and somehow find food for all those meals, so it's not like I lost any of my responsibilities and somehow know I have to figure out what the kids are learning, learn how to do it myself and find time to teach them and keep them on task.
The first week, I relied on both my boys when I'd asked if they had everything they were supposed to be doing for school done and they said yes, I took them at their word. This weekend I found out that wasn't true, they had just done what they deemed necessary and had put off the stuff they didn't know how to do until the weekend. Ugh. We got caught up on Geometry last night and I spend time organizing the next two weeks of assignments into smaller daily tasks for my 13 year old. He told me that he was sorry for not finishing everything and that he was just lost last week and it broke my heart.
This is so much extra to throw on our kids in this crazy world right now! I think we both felt better after I had my "lesson plans" worked out for him. He has one teacher who does his English and Social Studies classes is very organized and had everything already broken down into daily tasks for the kids in a Google classroom. His math and science teacher is only a 2nd year teacher and has struggled from day one, so he just gave them assignments and didn't teach them how to do anything.
So long stressful rambling later, I have no advice.

Bedtime is definitely a struggle, but again, I'm going to be way before them because I have to work in the morning and that's been that way before this whole COVID-19 mess. I get up and am at work by 6:45am and they aren't even out of bed yet when I leave for work.
