This book is an excellent companion to developing a unit of lessons based on dinosaurs. While this book is sparks children's imagination, it is also careful to point out the concept that dinosaurs lived on the earth a long time ago before people which can lead to factual based science lessons. This book can be used as a prompt for further investigation into expository text, support art activities, and encourage creative writing. Tomado de: http://amzn.to/1hfqPaA.
