DD9 was failing in 4th grade math last year. (Everyday Math.) I called over to the local high school and asked the calculus teacher if she had a girl who enjoys math and would like a tutoring job. She had several!
Once a week we met with this tutor (who was just lovely btw. Pretty, smart, a cheerleader, lots of friends, LOVED math!) and she sat with dd doing homework and going over multiplication tables.
We found that DD just needed someone who wasn't emotionally involved to sit with her for her homework. She shut down for dh and I each time we tried to help.
DD is loving math this year and is doing well! We still have a tutor for her once a week just to make sure that she is keeping up. It is well worth the $10 an hour!
