Here is the kit of uncolored originals for my Math for seven-year-olds project on Graph coloring, Chromatic numbers, and Eulerian paths and circuits.  Just print, copy each folio double-sided (with correct orientation, the cover is one-sided), fold each folio in half, assemble the folded folios side-by-side, and place into the cover to form your booklet, with a few staples for a binding.  See http://jdh.hamkins.org/math-for-seven-year-olds-graph-coloring-chromatic-numbers-eulerian-paths/

Andrej Bauer has assembled the images into a single pdf file: https://drive.google.com/file/d/0B7eG5PHUDcmZX1FnOHRhSU9ubUU/edit?usp=sharing, and filtered the color to black/white to improve printing.
