I placed students in groups and let them experiment with the stencils. The groups came up with as many prisms and pyramids as possible and glued them to the appropriate column on their "ancient" pink paper. They also kept the prisms and pyramids that didn't work and wrote about these solids and explained why they didn't work. I am so glad I went back and tried again. My students now have a "solid" knowledge of the shapes and can classify the prism and pyramid now!
