3D pens are a great place to begin learning about 3D design. 3D pens heat the filament inside, and it hardens shortly after it leaves the pen. Students can draw their designs freehand or use a stencil to build their construction.
Explore volume, perimeter, faces, and vertices by creating 3D shapes. Use a stencil for more accuracy such as this dodecahedron stencil. Tip: Laminate the page you plan to use as a stencil.
Design a 3D representation of your book character. This one is from the book, The Day the Crayons Quit.
