This book will challenge mathematical skills in a totally different way from the usual geometric puzzles. These 120 puzzles are visually intriguing. The book has 5 chapters, each one corresponds to a level of difficulty, from the very easy to the very hard. Even if mathematical puzzles are new to the reader, this book is a great place to start. Puzzle solving is not only fun; it will also enhance the reader's understanding of mathematics. More experienced puzzlers will also find very challenging opportunities. There are three types of geometry puzzles in this book: • No shape-based puzzles, i.e., they have triangles, circles, etc. • General shape-based puzzles, i.e., a hamburger, a bird, etc. • Japanese shape-based puzzles, i.e., a samurai, a bonsai, etc. The first chapter, “Solving a Puzzle”, offers a typical puzzle solved step-by-step. It presents how geometry is used to solve it, and the logical thinking leading to the solution. Puzzles should not only be fun in their design, but they should also be fun to solve. Their shape should be appealing to arouse curiosity in the reader. The information given to solve the puzzle should be as minimal as possible, sometimes to the point that the reader might think that it is not sufficient to solve it. This is part of the challenge of puzzles. All the puzzles have a step-by-step solution. The puzzles can be solved by geometry puzzle lovers of all ages. The puzzler does not need to be an ace in geometry to solve them. A warning: these puzzles can lead to a serious puzzle addiction! Enjoy the challenge!

Oxford International Maths teaches students the skills they need to become confident mathematicians. Students discover the joy of learning maths through problem-solving activities that stimulate their curiosity. Through an enquiry-based approach, Oxford International Maths encourages active collaboration, develops problem-solving skills, stimulates curiosity, and promotes a joy of learning. The topics covered ask students big questions and encourage them to make connections to the real world. Workbooks provide additional practice materials for classroom or home study. 'Example-problem pairs' exercises help students understand worked examples step by step, and apply their learning to another similar problem. Extra fluency questions support students with each part of the corresponding Student Book. Includes answer key, making it easy for students to check their work, self-assess, and correct.

Problems are presented simply and colorfully, and solutions are well expounded and clear. The reader will enjoy the challenge, and the "aha" moment of understanding any solution that they did not come to themselves. Great fun--and enlightening, too!
