I am more than a little bothered by the idea that we should only be teaching division to our very best. The original part of this strand was about how to engage students in a discussion so that they would understand algorithms. The example was about understanding division. So now we have before us a proposal that admits that it we may leave mediocre students behind but hhat is O.K.?
I really hope there is sarcasim in this reply that I have missed. I would hate to think that there are educators who believe, indeed even advocate, that we do not have a deep obligation to reach the "mediocre" students with basic mathematical ideas.
