What a great curriculum!
I have used this series in a 9 to 11 year old Sunday School class for the last 12 years. It is easy to use, understandable for the children and flexible enough to follow creative "bunny trails." It presents the Bible is a systematic chronological approach that facilitates the students memory retention. It is laid out so well that you can open the book and start teaching without ANY preparation time, although it is best to prepare for any lesson.
