Today is National Coloring Book Day. http://www.coloringbookday.com/

Who does not like to color?! Did you know that coloring can be very mathematical? The Four Color Theorem, which has a rich history from the 19th C to today. Read about the history at the Mac Tutor site listed below. Then, depending upon where your students are in their mathematical journey you can use the links below to find activities for basic coloring to investigating knots, networks and topology! Enjoy!

Four Color Theorem:

The four-color theorem states that any map in a plane can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color.

NCTM, San Francisco

My colleagues and I really enjoyed your presentation at NCTM.  We have already convinced our principal to pre-order us copies of your new book, but we would also like 4 class sets of the pyramids. 

Many presentations talked about problem solving and the benefits of giving students higher level thinking problems, but yours was the only one that really told us how to teach it and scaffold it for students, rather than just modeling what problem-solving looks likes.  Thanks.
