Brenda: As an old timer I would suggest not to worry about division,
especially anymore than two digit divisors. Convince the administration that with
calculators that is best left to that age. With the young ones, have you done
topology with the moebius curves? That always intriques them? Also, the base
two guesses of numbers. I make believe that I was at Hogwarts with Harry
Potter. When I guess the individaul number they each have in their heads, it
blows their minds. They all want to learn it. I use it as a reward if they do
their regular work.
