This hands-on book gives children the what, the how and the why to understanding the biggest challenges in the world --- one child, and one action, at a time!This interactive activity book shows children that they can help to make the world a better place. Divided into three sections --- people, community and planet --- each chapter is devoted to one of 12 specific challenges the world faces, from extreme poverty and universal education, to jobs and diversity, to clean energy and environmental conservation. Based on the “learn, think, act” teaching framework, it provides background information, fun activities and ideas for how to help solve each challenge. The goal is to pique children's curiosity about the world's challenges, engage their sense of responsibility, and empower them to do something --- a perfect recipe for creating engaged global citizens!With over 100 puzzles, games, craft activities, experiments and tips, authors and activists Karen Ng and Kirsten Liepmann seek to invite and encourage children to make a difference in their communities and the world. Throughout the book, children are introduced to keywords, concepts and basic information, broken down into manageable pieces and explored from a child's point of view. Covering science and social studies, this book provides a perfect jumping-off point for conversations about the environment, citizenship, local and global communities, economics, social justice and community involvement. Packed with curriculum-compliant activities, it could easily be tied directly to a classroom unit, with the class doing the activities together or as assignments on their own.
