It is hard to loose face to someone who is 12 or younger when you is a univesity gradieutte.
My fourth grade teacher insisted that only red blood cells were made in bone marrow because that was what the answer key said. She refused to look in the text book. I didn’t back down from wanting her to look in the text book, and she sent me to the Principal’s office. while the Principal didn’t explicitly back me against the teacher, at least in front o fthe teacher, I ended up being given a book to read.
Unwittingly, the teacher taught me an extremely valuable lesson: don’t accept what a teacher says merely because a teacher says it. At some point, years later, I realized what she had taught me, and became grateful for the experience.
The cursive thing and the “no late papers thing” are both things that I have more or less seen.

I noticed the puzzle fit of Africa and South America in second grade, but teachers back then taught reading and writing, not continental drift.
Gondwanaland.
I’ve got my own list. Multiple accusations of making up words, some of which aren’t particularly uncommon. One of my middle school science teachers was stupid enough to demonstrate that she couldn’t pass the tests she gave us.
