Only a simple black and white printer should be necessary to print out a coloring
page. It should print out centered on the page. These images were not drawn
freehand. I made them by gently securing photographs underneath good quality
tracing paper. I used both extra fine and ultra fine point Sanford Sharpies to trace the photographs,
with the aid of a straight edge for the math structures.
Initially, I began taking photographs of icosahedra and Sierpinski tetrahedra in natural settings with the intent of putting mathematics in a gentle visual light that would be inspirational to children. Many of the photographs turned out to be esoteric, so I made some coloring pages in an effort to put the photographs in a friendly, interactive format. Many of them also turned out to be esoteric. There are some exceptions. For instance, on the birds page, the first photograph is of two ducks, and its coloring page has a simple, friendly look with gentle lines. There is additionally a fence missing in the drawing, something a child can add to it. At a later date, I made coloring pages from photographs taken of children between the ages of three and twelve handling the structures, in all cases with parental permission. There are 101 printable coloring sheets spread across 22 pages, all are accessible from the dropdown menu above or the links provided below:
Building and Playing (8-year-old Lina):
Simple, step-by-step visual and written instructions for building a family of Sierpinski tetrahedra can be found on my Build Your Own Sierpinski Tetrahedra page (the iterative process is important here, i.e., building at least two consecutive structures as opposed to building only one structure) .
