Lesson Two — Building Paper Platonic Solids
- Print out the patterns for triangles, squares, and
- Photocopy them onto colored card stock.
- Score fold lines with a straightedge and a compass point
or a dead ballpoint pen.
- Cut out the shapes.
- Using the video as a guide, build each Platonic solid.
Experiment with different types of glue or use a stapler until you have a
technique that works. You can either hide the tabs on the interior or
have them on the outsides. You may want to trim the corners of the tabs
for the tetrahedron.
- You will also be learning to use the scene menus and the
slow-motion and pause buttons to control the video views.
- Once you have built all five solids, decide how much prep
work you want to do and how much the students will do in terms of scoring
and cutting out the shapes.
- Note: If you find the paper shapes too difficult to use,
you can substitute plastic snap-together pieces such as Polydron (see
reference on Links page).
- Display your paper Platonic solids for the students to
- Provide students with construction materials.
- Slowly advance through scenes from the video as you guide
students through the construction of their own Platonic solids.
