A couple of weeks later we told
our students:

We
want to revisit the ÒArea and PerimeterÓ problem. This is to be the basis for a
mathematics lesson that you will videotape yourself teaching
to one elementary school student.

How
can you present this task to the student you will teach? How can you set the stage
for the student to understand the problem? How far can the
student go in exploring this problem? Remember that you
want your student to discover as much as possible for
himself (or herself). But there may be some critical points where
you need to guide the student over an intellectual ÒbumpÓ so
that he (she) can move on to the next part of the
problem.

Finally,
produce a report analyzing the mathematics and your teaching experience.
