I get my little granddaughter after school and help her with her homework. Last year she was in 1st grade. One time she got an answer off by 1. She said it was ok because she was close. I told her don’t ever say that again, in math, there is no close, it’s either right or wrong. Every time after that, she’d catch herself and then repeat what I told her. She won an award for math.
Very nice. You must be proud!
