Not surprising.
Back in the 70's they began to teach math in a new way, in other words the most confusing mess you ever saw. I know because I was one of the kids they experimented on. Division left me in tears.
And then my dad asked me what the problem was and taught me how to divide in a single evening. It was simple, no guess work and you got the right answer every time as long as you knew your times tables and subtracted correctly.
I went to school the next day and flew through the work sheet. And got a zero because I had the right answer but had not used the hot mess of a guessing method.
The goal was not to teach me how to do division but to make me jump through nonsensical hoops.
Once again my dad came to the rescue. He went down to the school and had a few words with them. Upshot was that I was taken out of that school and they home schooled me for the few months we were there.
If the parents are having to "help" the kids with homework the teachers are not doing their jobs. At all.
One of the things I teach my kids about math, is that people who are GOOD at math are ALWAYS looking for ways to simplify, not ways to make things more complicated.
The teacher is supposed to teach little Jesse how to do division, NOT the mom. The teacher has 8 hours a day to accomplish that task. The teacher failed, so they say the parent didn’t do their job at night.
