Written for every middle school student, teacher and parent this unique title lays out a proven roadmap for building mathematics problem-solving skills from an early age. James Tanton, a Princeton mathematician, has created a delightful bag of techniques, strategies, and tricks to help students solve a wide assortment of mathematics problems they are likely to encounter on their middle school journey and beyond. Tanton uses 45 carefully compiled problems drawn from diverse mathematics topics to illustrate highly effective problem solving strategies. Based on his work across countries, colleges, and schools for the past two decades, this book is far less about making a student the ultimate problem-solver, but more about engendering an interest in problem solving and evoking a ‘Watson, the game is afoot!’ feeling in every young mind. A solutions manual with detailed solutions to every problem is available separately.
