And now Harvey Becker here again:

Judy....I agree with you! I absolutely don't believe that mathematic must be
justified in terms of practical immediate problems. My point above was in
response to Dan Hart's mentioning that he felt we should teach general
information before we ask kids to solve big complicated problems. I agree
with that notion. I think discovery learning has its place, but considering
the educational time constraints under which we find ourselves, I feel it is
fine to teach theory FIRST and then let kids use that theory to solve real
life problems SECOND............. OR just use the theory to use the theory.
Math has a beauty all to itself and need not be used to solve real life
