Great book! Because of the rhythmic repetition, students remember content easier. This is the first book that makes teaching character recognition in a useful manner. Great game opportunites exist. One thing that might improve it a little is more variety of rhythm schemes. But still a great book. Students may not remember proper tone markings on a test, but when using this book, they instinctively know when tones to chant are said incorrectly. Chants are much more useful than songs for the teaching of tones.
