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.

A smart and funny YA novel from Jennifer Honeybourn, When Life Gives You Demons Some people have school spirit. Shelby Black has real ones. Shelby Black has spent the past six months training to be an exorcist. Her great-uncle Roy—a Catholic priest—has put her through exorcist boot camp hell, hoping to develop her talent, but ohmygod, he still doesn’t trust her to do an exorcism on her own. High school is hard enough without having to explain that you fight demons for a living, so Shelby keeps her extracurricular activity to herself. The last thing she wants is for her crush, Spencer, to find out what she does in her off time. But Shelby knows how to keep a secret—even a big one. Like the fact that her mom left under mysterious circumstances and it’s all her fault. Shelby is hellbent on finding her mom, no matter what it costs her—even if what it ends up costing her is her soul AND a relationship with Spencer.

*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.
