My son is frequently in tears doing maths at home. Common core has some really stupid ideas.
I don't even understand their multiplication. Some weird 3d grid thing they're supposed to do.
I'll frequently say "look it's easy... Just do this..." and show him the easy way to do things and he'll say that we're not allowed to do it that way. The teachers tell the kids that if parents show them a different way they are to ignore the advice. Its crazy.
Also. Grades are given purely on answers (the teachers don't even look at how kids derived the answers... So how do they know if kids are doing common core or the way parents taught them).
When I was in school HOW you got your answer was more important than the answer. If you understood the concept but accidentally put wrong number down you still got most of the credit. Now its "we don't have time to look at what you did, just show us the answer".
Absolutely this ^

like the way we do a lot of snap calculations.
It's literally enough reason to up sticks and move elsewhere.
