You aren't doing anything wrong. Children are being taught these days that they have to be comfortable and happy all of the time. They are not being taught how to deal with people with different personalities or people who challenge them in any way. Everyone has to be "comfortable" and if they aren't it not their fault, its yours. No, wrong wrong wrong!
To get her to care a little bit more about math, maybe cloak it in science. I know my step son hated math, but loved cars, so if you equated the math problem into the car, or engine issues, he could do it easily! Show her how math can be related to science.
These days also, if your school is using common core math, good luck! Hell, I cant do simple arithmetic using common core math!!
Have you looked into a Montessori school?
