Re: [xmca] comognition some more



Well, my reading of this, Mike, is that A has not firmly fixed the two operations, + and -, and is simply getting them mixed up sometimes, about which rules she has to apply. Maybe at some point she has moved too fast from learning adding to subtracting while adding was not firmly learnt. I would take subtraction practice off the schedule for a little while.

They were the same as the problems I had helped her with the week before. I
asked her if she remembered how we added the two easy numbers together and
then added the third umber to that answer. She nodded yes and so that’s what
we did for all the problems. For example, if the problem was 3 + 3 + 7 we
added 3 + 3 first, which is six and then added the 7 to six, to get the
final answer. One thing I noticed, which I noticed before, is that A seems
to subtract a lot of times instead of add. So if I ask her what 7 + 3 is she
blurts out 4 really fast and then says, “no…” (Counts on her fingers) and
then says 10. I’m not sure why she wants to subtract but this seems to slow
her down a lot because she has to really think it through.

Again, ability presupposed by school and teacher are absent.
