Nim and the Powers of Two (VIDEO!)

Many popular texts in mathematics describe the game of NIM and the mathematics behind a winning strategy for it. The mathematics can be deep, and confusing, and not all expositions describe a simple and beautiful connection with the powers of two that makes all that complicated mathematics natural and easy. This video explains that connection!

    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!)
