So Much Fun And Very Informative
Format: Hardcover, Format: Hardcover
This book has been a winner in our house since it arrived. Each page has so many flaps, spins, pulls and movement. So many new words and easy explanations for the kids. The pictures are beautifully designed and each time we look through it we find more details we missed! The book is an excellent purchase and definitely worth every penny!

Best Construction Kids book
Format: Hardcover
My nephew can look at this book for hours. It is such a cool book even for adults. It is a more delicate child’s book as their are lots of demonstrations and paper pieces that move. The house across the street is being torn down and rebuilt and he will sit and point to the book and say this is what they are doing today. I think this book is one of my nephews most prized possessions. It’s a great book that can grown with them for a few years. He is only 3 but this could easily engage a 5 or 6 year old. There is lots of details and the book is really well designed.

Fun, but fragile
Format: Hardcover
This is a cool book, and my 2.5 year old son LOVES it. However it is important to note that it will be destroyed very quickly. There are lots of flaps and moving parts and it is very easy to accidentally rip them off if you try to move one in a way it's not meant for. I ripped more than 1 myself.

Great for training
Format: Hardcover
I order these for new salespeople and managers who have no construction experience. They think it's a joke until they start going through it.
