A Gory Puzzler (VIDEO!)

Here is a classic, but gory, puzzler of life and death for gnomes. This video comes in three parts, the STATEMENT, a HINT, and the SOLUTION, so pause at the appropriate moments to dwell on the puzzle before I give it all away.

This puzzle appears in chapter 5 of the first volume of THINKING MATHEMATICS, and I also included it in “A Dozen Hat Problems” Math Horizons, April 2009, co-authored with Ezra Brown.

    Written for educators - and their students too! - this website, slowly growing, takes all the content Tanton has developed in his books, videos, and workshops, and organizes it into short, self-contained, and complete, curriculum units proving that mathematics, at all points of the school curriculum, can be joyous, fresh, innovative, rich, deep-thinking, and devoid of any rote doing! Let's teach generations of students to be self-reliant thinkers, willing to flail and to use their common sense to "nut their way" through challenges, to assess and judge results, and to adjust actions to find success. (Great life skills!)
