Book excerpt: Readers will dig these books! Groovy Tubes offer more than just a book, they allow children to learn on many levels through reading & playing. An educational book, with fascinating facts, zany illustrations & photographs or realistic art, provides the base of this three-tiered package. Activities at the back of the book & a game board folded into the box with fact-filled quiz cards will provide hours of fun. The play creatures in the spine tube extend the learning in a tactile way, as all components work together to familiarize children with the subject matter. It's been millions of years since the last dinosaur roamed the Earth, but dinosaurs remain the subject of much fascination & study. Dino-Might! teaches what dinosaurs ate, where they lived & how they defended themselves. Also included are possible reasons for their extinction & a timeline that shows the different eras.
