... conduct several imaginative explorations to investigate
angle measures and their relationships in triangles,
quadrilaterals and other polygons. Using drawings
and tables to organize information, teachers find
ways to generalize a rule for finding the sum of
the interior angles in any polygon.
Workshop 6: In Practice,
Learner Teachers ...
... discuss how they taught the Polygons & Angles
lessons in their classrooms. They learn to evaluate
different types of scoring guides and determine
how to use them most effectively for evaluating
student work. Finally, small groups of teachers
begin to develop new culminating projects that
target specific mathematical goals and objectives.
the following pages, we offer agendas for two
different levels of professional development:
