Subject:   bouncing accuracy

Pedagogically, I assumed that the message would confirm accuracy for the
equation only if the equation tracked the ordered bounces.  My surprise gives
way to a question of whether, perhaps, the set-up reinforces the commutativity
of addition and helps kids feel more at home with negative numbers--they "act"
like what the students have already come to know as "numbers."
