I can say that I have been in your childs situation. For me, I just didnt understand it, and it was pure torture for me. School in general was a nightmare, with math topping it off. Maybe like me, your kids situation is not that he doesnt want to understand it, but CANT!! Like me, all the numbers would and still do get "jumbled" in my head. The worst was when the teacher would put me at the chalkboard, and I didnt understand it, or would count on my fingers, and all the kids would yell at me that I was stupid. This was NOT a condition conducive to a positive learning environment. This went on for almost the entire year. Did I mention that this was for 9th grade math? One day I got so frustrated with all the jumbled numbers in my head that I chucked the Algebra book accross the room into the wall. They took me out of that class. They had NO business putting me, with a 3rd grade math knowledge in a stinking Algebra class! I am now 45, and I still have a 3rd grade math knowledge. I DID graduate HS(diploma) but I had to be in a lot of special education classes throughout school. No, I did not attend college, but went into a vocation(not Goodwill) that I have been at now for 22 years, and been successful at it.
