I recently bought a book for my kids to read on the train trip to Kuala Lumpur. Its simple story will appeal to those 9-12 years and is published by Scholastic Paperpack. It a great read for kids who are just starting their martial arts classes. The book titled “The Karate Mouse” has a good section on the Dojokun and also a vocabulary section that explains karate terminology. The illustrations are very funny and will entertain the kids. You can buy the book online from Amazon.com or from your local bookstore.
