Well, my DS2 (3rd grade) started back hybrid last week. Two days per week in person, two days remote/ asynchronous learning, one day zoom.
It's still early, but so far I LOVE it. So much better than full remote. Full remote was always a battle of getting him to pay attention and THEN do his work and THEN do his homework. Writing especially.
He literally had not seen a single friend in person since last March 13.
So, the 2 days he has been in person so far, he's come home exhausted.
We are on day 2 of "asynchronous learning", which starts with an in person zoom of about 10-15 minutes to go over the day's work. He has his 3 specials on these days (art one day, PE/music on the other). Otherwise, he has math assignments to complete, writing to complete, and reading to complete - just like it was when he was in class.
But SHOOT - he just...does it? Far less arguing than before. Even his WRITING!! Okay, getting him to pick a book to read (we have dozens at home) is a challenge. He also still has homework after lunch time, which is some online assignments and more reading but MAN.
I don't want to jinx it, but it's working so much better for us and I can actually WORK. I can concentrate on the days he is at school, and even on the days we are sharing the "office" (the kids' bedroom).
