* below long* tuatara, for me, it isn't obvious that 25 x4 and 4x 25 are the same problem; I also didn't know that the dollar is worth a hundred cents.
There was a time where I wouldn't have been able to see how 4 quarters is the same as a dollar...the way I still often trouble is - someone shows or tells me something spatial-manipulative related, and if I heard it, I don't process it. It's like the information is put into a strainer and simply drains away, or evaporates almost instantly. If someone physically shows or models something for me, I'll have a much better chance of "getting" it - but that is relative the audio processing issue. Someone can still show me and when I attempt to model or copy what was done, I can't translate that into -me- doing it. Or in either a visual or aural sense - if I get it the first time, the next time I'm expected to know what was explained, I have -nothing. I think in pictures, if I have no picture, then there's nothing for me to go on. Part of the reason why word problems have always been such a problem, I don't process them and I if I do process them, I often don't have the pure math to be able to work the math in the problem.
I recall sitting in class in second grade, everybody working on "rounding". and the symbols, which I never figured out.. could NOT for the life of me understand that rounding! As in most math classes for all of my school years, I sat in that segment about rounding with the book open and nothing making sense. Everybody else got it and I was totally, utterly lost and disconnected from that understanding. It was like the teacher was speaking Thai. If asked to explain what it was I didn't understand, I wouldn't have been able to explain that either. I was socially and emotionally behind and awkward and just didn't have the words to explain misunderstanding...got me labeled as having "math anxiety" during high school Geometry. I was sent to counseling with the school guidance counselor :roll:
