Seventh Graders Build a Dodecahedron!

Just before Spring Break, the 7th grade French math students worked together to build a huge 3-D dodecahedron.

A dodecahedron is a convex, regular polyhedron with 12 pentagonal faces.

First, students had to figure out how to draw the largest possible pentagonal faces on the cardboard we were using as our building material. Then, they cut out the pentagons, and began the complex process of assembling them into the dodecahedron.
