"Daydreaming Davey's Dinosaur Math Adventure" has a cute premise--in that it gives a few mathematical examples where the reader is asked to count the number of dinosaurs in a given picture. It also teaches a few interesting facts about the brachiosaurus and the pterodactyls dinosaurs.
The book is short and only a few mathematical examples are given. An adult could use the book to create more examples, but children get bored after reading the book, as written, a few times since they tend to memorize the examples. It is a shame that the book doesn't contain more examples of counting, as that would make it more valuable as a teaching tool.
I read this book on a Kindle, and would not recommend reading it electronically. In the electronic version, the dinosaurs often blended in with the background pictures making it difficult for an adult to count the dinosaurs. Needless to say, this made it even more difficult to teach a child how to count.
