Thank you for all of your input on this matter. I will definitely check out the books that was suggested. Thank you arlen1.
I am sorry for the confusion on the IQ test. He took WISC-IV not III, I must have been thinking WIAT-III when I typed that.
Does anybody know, in WIAT, whether total math is the combination of mathematics and math fluency, or just mathematics? His math was 155, but his math fluency was 107. At the time of test, DS was able to figure things out how to calculate things, but we never really work on fluency, not until the school required him to. I'm still trying to decide whether to have DS take another test or not.
