This collection of puzzles, games and activities is designed to stimulate and challenge people of all ages who enjoy puzzles with a mathematical flavour. Many of the puzzles have a long history, while others are original. The subjects vary from matchsticks to magic squares, train shunting to river crossing, and chess to calculators. The second part of the book contains a commentary giving hints and solutions.
I keep seveal sets of different small books like this (in multiple copies) for my 9th grade math students when it comes time to do display projects and make vocal presentations. This one fits very well into the scheme when it comes to short items. Class is always attentive (more than to me!).Well illustrated, big print, and 130 puzzles (with solutions in the rear) of which I easily suggest about 4 dozen for project use, and others for personal or small group amusement.
