My friends are having the same issues as you are with Mini-B. 7th grade is the hardest grade. They go from being treated like little kids to being treated like they are nearly adults and are expected so much more out of them. They expect them to be able to take notes, right down all assignments and don't care if they get 30 assignments that are all due the same week. Heck in college the teachers did try to spread things out so they didn't dump all at once, but 7th grade too bad so sad is the attitude. Their excuse has always been we have to prepare them for high school.
Hopefully the ex-TB fines out something or at least gives the teacher a piece of her mind. I know with the older kids I lost it on one of their teachers in 7th grade. To the point that she never spoke to me again.
So far from my friends the kids have lost all electronics until grades are up to the parents expectation.
Can I say I love homeschooling
Good luck with the new morning routine.
