Designs derived from the original article "Pull-up Patterned Polyhedra: Platonic Solids for the Classroom" by Meenan and Thomas. Carlos Páez built the solids and created this demonstration video:

The teacher Sonia Medina Pérez was one of the first to build them with her 4th grade students, as she shows in her video:

This is a new approach to the teaching of three-dimensional solids. We focus our attention on Platonic solids (the tetrahedron, the cube (or regular hexahedron), the octahedron, the dodecahedron and the icosahedron). We try to promote the teaching of two-dimensional and three-dimensional geometry in a visually stimulating way. It has been found that the material attracts students of a wide range of skills, and is especially aimed at those between the ages of 10 and 16. These designs provide an important visual stimulus to students who build them. The exercise shows the transition from flat shapes, which are the faces of a polyhedron, into a solid form. Geometric connections are thus made, and this allows the student to cross the visual bridge between two- and three-dimensional space.

Download and print the sheets and assemble them as shown in the video and in the images. Use this link to download the PDF [PDF Document] to print the designs and then assemble them.
