I did not put an age level on this book. I would say its for elementary age children, however, my daughters and I worked out of this book as part of our home schooling and my high schooler enjoyed the projects just as much as my 4th grader. The book is in good condition, but please note that this is a library discard. The library put a taping around the binding and the binding is covering the library bar codes etc
