The Color Code of the Platonic Solids will be my first book designed for children who should learn the platonic solids in elementary school. This book will have cutouts, with a removable insert, so children and adults can have a fun project together cutting out and asseembling while learning the properties of the Platonic solids and the elements they represent.
Draw a Dodecahedron
If you want to get a hands on feel for 3d geometry, take the time to draw a 3d Dodecahedron on a 2d platform. It was my humble beginning.
