Does anyone have Harkness style teaching questions for Geometry? I'm looking for problems starting with simple and going through the standard topics of Geometry. For instance, on comparing line segment lengths, I ask: "Who is the tallest person here? Who is the shortest?" This requires each student to think of herself briefly as a line segment and to compare each other to each other. I also ask: "Who has the largest head?" and imagine that someone will come up with the idea of wrapping a string around the brow and then comparing the lengths, as if measuring a hat size.
