Most of us can tell the difference between a reef knot and a granny, but can we tell when a knot is not a knot at all, but an unknot. Through a series of interesting puzzles, Heather McLeay leads us gently into an understanding of the theory of knots.Many of them can be solved by looking and thinking, but for others, having a length of real string or rope to hand would be a great help. In all, this is a colorful and original book, offering a delightful introduction to knot theory. It is one which will appeal to anyone with a liking for puzzles and an interest in curious ideas of a mathematical nature.

Problem Solving Strategies Crossing the River with Dogs and Other Mathematical Adventures Why Teach a Course in Problem Solving? The NCTM Principles andStandards state that problem solving should be integrated throughout all courses and grade levels. For example, guess-and-check is a natural strategy to apply in algebra. Advanced math students often use finite differences to study functions and sequences. And drawing a diagram and using physical representations are commonly employed strategies in many contexts. However, many students never encounter valuable strategies such as matrix logic or unit analysis. And in content-crowded math classes, few students get the concentrated practice or time necessary to fully develop their problem-solving skills. By taking a semester course in problem solving, students can master a multitude of strategies while developing confidence in their problem-solving abilities. Your students will be better prepared to meet the challenges of school and life by taking this course.
