As a mathematically challenged person, I can relate to your daughter's issues. To reinforce counting money, ask her to help while shopping (If we have $3, and these cost $1.29, etc.). The great thing about math is that it gets better with practice. Keep practicing.(I still am, and Im 26! lol) Talk with her teacher and see what she is required to know by the end of the year, and go from there. Ask a LOT of questions, but also reinforce at home. Like someone said, certification doesn't always equal a great teacher.
Just my opinion...
