From your other posts, I know you have a greater than typical amount of complexity happening. Please, take a deep breath (or several) and try to remember that this is a tough moment in time but that things can get better. For what it is worth, our PG (not 2E) fourth grade child was from A-F as well at midterm. As in the fun (music, gym) classes and one F because he forgot to turn in an assignment and didn't do well on a few others. Right now, he's from As to C+ (some additional effort on his part plus the opportunity to get more points as the term progressed). Perhaps your son will show up at the higher end of the range when finals come.
Ask yourself and your children, if you step back from grades (which are so far overblown that they become the goal or seem to be, seems twisted to me), what is being learned? Are they understanding the material? If not, how can they do so? Making notes about some of these things can help. I hope, too, that you and your children can take some time to enjoy each other, without fretting about school. (Yes, you have every reason to be upset and there are real issues, but make sure that they know they are fully wonderful humans all on their own, regardless of the schooling issues.)
