Re: Praxis ii middle school math - Three Personal Examples
Posted by Pragmatic on 4/28/08
Box-and-Whiskers is relatively new in the curriculum. I too hadn't seen it when I was a wee lad. I think of them more as statistics (I never did stem-and-leaf plots either), rather than math. They're a way of representing large sets of numbers, but I don't think that there's a lot of math in it. Transformations are new for middle school, and not very worthwhile, I think. They talk about them, but they never introduce the concept of a 'rigid motion in a plane' nor the idea of what can and can't be done within a certain set of transformations. I feel that it's more a 'playing with shapes' activity than any real math. (Don't get me wrong on this. There's lots to be said for playing with shapes. I just don't think that we have time for it in a middle school math class) I know I did inequalities many times. Unfortunately, m inequalities' solutions usually boiled down to "solve the equation as though it were an equality, then check (0,0) to see which side to shade". There were some trivial problems that could be solved by inspection, but anything that required work lent itself to too many opportunities for error compared to the try-a-couple-of-easy-points solutions. I think of the data representations as being artifacts of notation and vocabulary, rather than "unseen" math. I also didn't see lattice multiplication growing up, but math is math, and once my 3rd grade nephew showed it to me I saw what was going on. I still don't agree that it's a better tool than traditional math, but I doubt I'm going to convince any elementary school teachers to change their ways when it's district mandated curriculum.
