A Classroom-Tested, Alternative Approach to Teaching Math for Liberal Arts Puzzles, Paradoxes, and Problem Solving: An Introduction to Mathematical Thinking uses puzzles and paradoxes to introduce basic principles of mathematical thought. The text is designed for students in liberal arts mathematics courses. Decision-making situations that progress from recreational problems to important contemporary applications develop the critical-thinking skills of non-science and non-technical majors. The logical underpinnings of this textbook were developed and refined throughout many years of classroom feedback and in response to commentary from presentations at national conferences. The text’s five units focus on graphs, logic, probability, voting, and cryptography. The authors also cover related areas, such as operations research, game theory, number theory, combinatorics, statistics, and circuit design. The text uses a core set of common representations, strategies, and algorithms to analyze diverse games, puzzles, and applications. This unified treatment logically connects the topics with a recurring set of solution approaches. Requiring no mathematical prerequisites, this book helps students explore creative mathematical thinking and enhance their own critical-thinking skills. Students will acquire quantitative literacy and appreciation of mathematics through the text’s unified approach and wide range of interesting applications.

Challenging collection includes some of the worldrsquo;s most perplexing brain-teasers by such masters as Sam Loyd, Johnny Eck and Henry Dudeney. Also, the stories behind the creation of the puzzles, the worldrsquo;s earliest riddles, the birth of the crossword puzzle, much more. Introduction. 146 illus.

Steam Trains and Jigsaw Puzzles strikes most people as an intriguing title. The origin is simple,however my trainspotting youth has been synchronized with a later interest in jigsaw puzzles. The result is expensive I have a collection of over 250 jigsaws depicting British steam railways. The conclusion is impossible there are over 500 steam railway jigsaw puzzles to collect and they are being supplemented annually. The Liverpool & Manchester Railway marked the arrival of the true passenger railway service in 1830 and presented jigsaw manufacturers with another subject on which to focus. Prior to this date the jigsaw experience, started by John Spilsbury in c1760, was restricted to subjects such as religion, geography, history, monarchs, the alphabet and art. Many characteristics combine to form the basis of nostalgic images buried indelibly in the minds of people who travelled in the steam railway age. Manufacturers have not been slow to tap into this nostalgia and produce jigsaws aimed at stirring those memories and inviting people to reflect on past experiences, good, bad or indifferent. Chad Valley, Victory, Good Companion,Falcon, Waddingtons and Arrow are just a few manufacturers who produced steam railway jigsaws in the past. Most of these companies are now a distant memory while others are in foreign ownership. Equally famous names such as Wentworth, Ravensburger (Germany), House of Puzzles, Gibsons, JR Puzzles and King Puzzles (Holland) continue the manufacturing tradition. Output is generally superb thanks to the efforts of fine railway artists such as Terence Cuneo, George Heiron, T. E. North, Don Breckon, John Austin, Barry Freeman and Malcolm Root. The book is aimed at anyone with an interest in jigsaw puzzles and at those enthusiasts and aficionados who refuse to allow those evocative memories of the Golden Age of Steam to die.
