not sure what was going on in her mind. as an educator, if i had to choose between efficiency and understanding, i would prefer understanding. you can get Microsoft Excel or perhaps a Cray to do the calculation if you really want efficency. if she was trying to figure out on her own 10 - 7 = 3 as another way of saying 3 + 7 = 10, then i'd say that's good news, because personal agency in learning interconnections and relationships is what maths learning is really about, IMHO. regards, F.K. 2009/5/24 Mike Cole <lchcmike@gmail.com>: > Another example of a struggling kid and how the strugggles manifest > themselves in talk and action. > > They were the same as the problems I had helped her with the week before.
