Foreword
THAT I WOULD BE writing a Foreword for a book on teaching math seems at
once both ironic and absolutely appropriate.
Th e irony stems from my long and generally unhappy life as a math student.
In elementary school, math was neither easy nor hard for me. It was simply some-
thing I did. It evoked neither pleasure nor pain. I suppose it was a bit like household
chores—something necessary to get through the day, but certainly nothing to be
coveted. Th rough those years, math was as rote as household chores. I memorized
the required number sets, counting, and multiplication, absorbed algorithms I
watched my teacher scribe on the blackboard in the front of the room, and repeated
what I saw. Th ere was no joy in it, but it was doable.
Once I entered the world of algebra, however, math became a sinister thing.
Letters invaded the numbers. Equal signs took on a super power. While I could
occasionally duplicate what my teacher chalked in front of us, I could no longer
commit the strings to memory. Th ere was no reason to them, and worse, I didn’t
even really grasp the notion that they were all about reasoning. I simply knew that
I could no longer succeed with math. Th e conclusion I drew, of course, was that I
was no good at math.
I received a one-year reprieve from my self-imposed verdict when geometry
intervened between Algebra I and Algebra II—and before trigonometry had its way
with me. In that one year, math was glory. In that one year, math was about reason-
ing. Th ere was order to it, like the order in the universe. Th ere were words that
marched along with the fi gures and problems. I loved it in the way that I loved good
writing. It revealed beauty and it dignifi ed my possibilities as a learner rather than
eroding them.
But the interlude didn’t last long enough to erase the damage done earlier or
to reconfi gure my sense of myself as outpriced by math. It took many years for me
to realize that the dismay I felt in the presence of math was neither a fault in me
nor an indictment of math as a content area. Rather, I came to see myself as one
among a legion of students who had abandoned a content area—or even school—
because the way a subject was taught drained all the life from it, even as it drained
life from the learners.
Th e appropriateness of my writing this Foreword is, of course, not completely
separate from the irony. I have spent my career as a teacher (an English teacher, to
be clear) and then as a professor with an evolving belief, then a conviction, and
