Fold and Draw Geometric Shapes

Watch a webcast of teachers learning how to teach the properties of
two-dimensional figures. The introduction explains the general
overview of the webcast, and the succeeding segments go into deep detail of why
paper folding helps students understand geometric figures, and how to use paper
as a visual and kinesthetic tool.  One segment goes through the van Hiele
Taxonomy of Geometric Thinking as a way to follow a student’s progress through
the steps of understanding.  After the lecture segments, watch students in
classrooms working with paper and compasses as they explain what they are
learning.
