The Puzzle Corner and Maximizing Math activities this month are two parts of one problem - a variation of a teaser problem that appeared in the March, 2003 Games magazine. The orginial version describes a five-volume set of books that have been reshelved in descending order, from five to one. The challenge is to put the books in order from one to five using the fewest possible number of moves. Each move consists of changing the location of two adjacent books. Our version of this puzzle is a little different.
