Triangular Santa

I thought - let's get a lettle geometry into Christmas. My sixth grade
class is familiar with some basics terms and shapes, and my seventh grade
class is more advanced.
I started out with a rectangular red piece of construction paper (12" x
18") and told the children to draw the largest circle they could using
their compass. They clearly marked the center of their circle. Next, we
cut the circle out and talked about the parts of a circle. We then folded
the outer part of the circle to the center three times in order to give our
Santa some firmness. Then, we talked about the equilateral triangle we
had, and I made sure they knew what the vertex was. We then proceeded to
fold each vertex to the midpoint of the opposite side and all of a sudden
they discovered we had a triangular pyramid. We discussed this figure and
identified vertices, faces, and edges. Now, the real fun begins. We used
a hole puncher to make three holes about two cm below each vertex of the
initial equilateral triangle. The children then drew a small triangle with
white chalk on a select face of the figure. On this white part we glued
two moveable eyes and drew a red nose. From cotton puffs we trimmed
Santa's hat, gave him a beard, mustache, and a pom pom on his cap. Lastly,
we put ribbon through the three holes and we had our triangular pyramid
again and our finished Santa.
I have more folds to this basic pattern, so I'll post them at a later date.
I hope this is useful to someone.
