This picture book is a great teaching tool for vocabulary building. A set of wonderful pictures show exactly what a dinosaurs looks like. It is like a dictionary of dinosaurs for toddlers. The pictures are clear, the colors are nice, the letters are big enough. It's excellent for your little one to helps him build confidence in his ability to "read" the letters from A to Z (shown on the pages for the words shown that begin with them).The best thing about this book is the wonderful illustration of each dinosaur - clearly labeled with it's name. As you read this book over and over to your child it won't be long before they are the ones pointing to the picture and telling you what it is. Just point and say.
