In Elementary Mathematics Education David W. Jardine University of Calgary with Sharon Friesen Rockyview School Division Car ride to school. And I'm quizzing my 14 year old son, Eric, about how math is going lately, what they have been doing, whether he understands. I have been working for the past few years with Sharon Friesen and her teaching partner, Patricia Clifford, who have been working both in elementary and middle school classrooms over the past few years. Equivalence becomes, not a question but a state, a point of rest. It loses some of its compulsiveness.
Equivalence is now no longer an operation.
It no longer longs or waits or demands to be done . It no longer needs us to do it. We need no longer be actors or manipulators or constructors drawn into the frays of action and manipulation and construction. As this once-taunt pendulum now rests in equivalence, we, too, can now rest in it . So now, a new pleasure arises to replace the tensed pendulum jitters.
