Most girls don’t do as well in math as they do in wordy subjects. She’s just going to have to work really hard. Also, I would suggest asking the teacher for sample tests to practice with.
I can’t speak for most girls, but she’s always done well in math. Last year she was one of only a few in her school to get a perfect score on both the state math and English language arts tests.
Garbage, total garbage. Mac, do NOT let your daughter listen to opinions like this. Many girls are very gifted in math, I was, and being told "girls don't do well in math" (all they hear out of a statement like the above) just offers a reason not to try.
Specifically, no advice except if you can, get her out of that school and into private or homeschool. But that's the same advice I'd have for any parent. Perhaps write an email to the teacher outlining your concerns about the test portion of the grade and cc it to the principal?
