Foam Pyramids

More from my fun with folding series:  after having fun making paper pyramids, I thought I’d try out foam board as a medium.  As before, I began by connecting the midpoints of the sides of the triangle to form its medial triangle.

Then I scored the medial lines, bent, and taped!

A rotation gives a sense of how oblique this pyramid is.

My students and I enjoy exploring questions like “Will this procedure always produce a pyramid?” and “What other kinds of solids can be formed in this manner?”

Have more Fun With Folding!
