I purchased this product for my children because I wanted to give them a tool for learning sign language. I have been learning ASL and I want to be able to use sign for communication with my kids as well, so I knew (since I know Tara) this would be a great resource. The kids are fascinated with this book! It is so fun to see them trying out the signs. Since buying the book I realized that it not only teaches sign language, but includes valuable information about deaf culture that really should go hand in hand with learning a new language. Tara Adams is such a gifted teacher! The illustrations in this book are also clear, easy to understand, and appealing. I would highly recommend this book.
