My 3 grandsons 8 to10 years old enjoyed the activities in this book very much. They definitely had more fun working with others - cousins with their own books or grandma watching and laughing with them. Even a creative child may need to share with a friend or parent to get the most enjoyment.
It gets 4 STARS for the kids since I'm not sure if they will continue working on the activities without the "sharing".
It would get 5 STARS from me because the activities are not only fun but also describe their lives and personalities (which they loved sharing). It would be well worth the time a parent would spend sharing - saving the completed activities to be read and laughed over later or passed on to THEIR children (or even a gift for a grandma!)
