Mike - My son is the flip of yours. Sucks at Math and does great with spelling reading and writing.
If frustrates me because I am good at math but I have a hard time teaching it. I just know it from studying.
Thanks Steve for the Abacus tip I am going to look into it.
What frustrates me with Trig is the fact that you will almost never use it in life. If you need to use it, you will use a computer to figure it out. I agree that you should understand what you are doing but I have seen persons with no math background do very well in Land Surveying (Trig at its finest in every aspect) as well as someone who has a strong math background.
I know it needs to be taught but in all honesty I have forgotten a lot of what I knew from not needing to use it anymore. I have computers and software to do the job for me and its a lot faster and more accurate too.
Mike - we signed our son up at an afterschool tutor. It was to develop cognative skills though. Something schools use to teach and have moved away from. The school was called Learning RX

It made a world of difference in my son. I highly recomend it. It was very expensive but worth every penny as far as I am concerned.
