My husband, who is a computer programmer said, "I want to own this book." This book is an excellent tool to introduce computer programming to your kids. Age 6 and up would benefit from this lovely book. Be warned though, the book is most effective if one of the parents is an actual programmer. Regular folks would be able to use it, but to make the most out of it, it's best if a parent/tutor is familiar with computer programming. I'm excited for the kids who would take an interest on this book, highly recommended! This book came out in May and I already ordered this book for our library!
