One-Osaurus, Two-Osaurus
(Book)

"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"--
