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?”
