Hashi (short for Hashiwokakero, meaning "build bridges") is a new logic puzzle from Japan. In Hashi, the goal is to join islands together with up to two vertical or horizontal bridges, so that every island is connected. The larger in number value the island, the more bridges connect to it (an island of size 6 must be connected to 6 bridges), and no bridge can cross another. Successful logic puzzles have certain things in common: a unique game with one solution, easy to pick up, fun and challenging, able to be put down and picked back up again. Hashi has all these qualities, and puzzle master Alastair Chisholm has created 201 puzzles in three levels of difficulty--Easy, Medium, and Hard; you'll be thinking about them even when you're not working on them.

Hooked on su doku? Then move on up to kakuro! Kakuro is the latest Japanese puzzle craze for all those who thought they had reached the limit in logic puzzles. Kakuro is all about numbers, and like su doku it is solved by using logic, with absolutely no guesswork. However, Kakuro takes puzzling a step further: it requires simple arithmetic skills as well as reasoning. But don't worry if maths isn't your strong point. While some of the logic relies on you being able to add up, the sums only ever involve a few single digits, and the totals in this book are never more than 45. You don't need to be a maths whiz, nor do you need to have a calculator handy. You will have no difficulty in doing the sums in your head. As with the incredibly addictive su doku, the fun in doing kakuro is working out the logic that gets you from the starting position to the single solved grid of digits. So if you're bored with su doku - kakuro is the next logical step . . .

*THIS BOOK IS AVAILABLE AS OPEN ACCESS BOOK ON SPRINGERLINK* One of the most significant tasks facing mathematics educators is to understand the role of mathematical reasoning and proving in mathematics teaching, so that its presence in instruction can be enhanced. This challenge has been given even greater importance by the assignment to proof of a more prominent place in the mathematics curriculum at all levels. Along with this renewed emphasis, there has been an upsurge in research on the teaching and learning of proof at all grade levels, leading to a re-examination of the role of proof in the curriculum and of its relation to other forms of explanation, illustration and justification. This book, resulting from the 19th ICMI Study, brings together a variety of viewpoints on issues such as: The potential role of reasoning and proof in deepening mathematical understanding in the classroom as it does in mathematical practice. The developmental nature of mathematical reasoning and proof in teaching and learning from the earliest grades. The development of suitable curriculum materials and teacher education programs to support the teaching of proof and proving. The book considers proof and proving as complex but foundational in mathematics. Through the systematic examination of recent research this volume offers new ideas aimed at enhancing the place of proof and proving in our classrooms.
