[[[[[But *then* we teach the long division algorithm, and some of those same
students who once knew how to divide $2 among eight people will now try 2/8
and end up with answers such as 4, 2.5, and 25. What's worse is that they
often *trust* these answers because the algorithm was handed to them on a
silver platter with the implied message that "this is how people
divide."]]]]]]

Well yes....but anyone who fails to learn the algorithm correctly deserves to
get 4 and 25 as answers to 2/8. Why not learn it correctly and get .25 as an
answer? .......Since, as you say, they already know that 2 bucks divided
among 8 people is 25 cents each....they should know that they blew the
division algorithm when/if they get 4 for an answer. I am not for dishing
out algorithms blindly....kids must have a number sense about them and an
ability to estimate so that such "crazy" anwers as 2/8=4 do not happen when
attempting the division algorithm.
