This puzzle challenges players to flip sixteen counters, which are black on one side and white on the other, into an alternating pattern -- in the fewest number of moves.
|Hints for uses in your library||Create your own puzzle set using a set of "counters" (available as math teaching sets) or use two-color plastic disks, such as from the game Othello. The interview video in the links below set up this activity in an engaging way; have the video available for participants on a tablet or computer. One puzzle set and video could be used by a single participant or family at a time, or multiple sets could be provided for a facilitated group activity.|
