Part counting game, part dinosaur celebration, this energetic romp is a numbers concept book for the ages.

One-osaurus, two-osaurus, three-osaurus, four!

Look there, in a child’s bedroom, where some prehistoric pals are gathered in a counting game. Nine dinosaurs are playing a sing-song rendition of hide-and-seek—but something isn’t adding up. Where is number ten?

Stomp, stomp, stomp! CHOMP, CHOMP, CHOMP!

Ready or not, here he comes, and he sounds . . . big! With big, bold numerals, an array of dinosaurs in comical poses, and a humorous twist at the end, this tribute to a child’s imagination makes learning numbers a gigantic treat.
