This book is a high quality (in its construction, printing) flip the flap book for older kids who are by nature curious and who enjoy attention to detail.
Unfortunately, it can be challenging to explain many of the (not simple) concepts on the fly when the explanations in the book are extremely truncated. Which, (although I couldn’t have done any better myself), is somewhat of a pervasive problem with this book. So, somewhat disheartening for little learners, even though it’s fun to flip the flaps.
I’m thinking the boys may learn a few helpful things along the way with this book.
