Your daughter sounds like mine when she was that age except she had problems with reading as well. You said she is 7 which makes her younger than many of her classmates. My daughter was young compared to the other students as well and she struggled throughout grade school. She did not truly catch up with the older children until I sent her to private school in junior high. As far as holding her back, they would not. We were under the no child left behind administration. Better known as "We won't pay to have your child repeat a grade. We don't care if it would help her." Nevertheless, from what you said your daughter is only having trouble in one area. Your frustration and fear may interfere with your ability to coach her. You may want to find a tutor. Someone with a fun and relaxed attitude may have very beneficial effect on her. Recommendations from your school, parks and rec from the city you live in, or your local high school, or community college maybe a source to find one for little to no cost. Good luck.
