This engaging tale is perfectly pitched for preschoolers and for fans of Byron Barton's Dinosaurs, Dinosaurs and Jane Yolen's How Do Dinosaurs Say Goodnight?

A group of young dinosaurs builds a seesaw and takes turns playing on it until the bossy, big, and TERRIBLE Tyrannosaurus interrupts their game in a fit of temper. All ends well, though, when Mom steps in and encourages a peaceful and a productive end to the conflict.

Hyewon Kyung's detailed and humorous illustrations will capture the attention of dinosaur fans, and a dinosaur information chart and educational backmatter about simple machines make this perfect for classroom, family, and story-time sharing!

"I'm bigger than you!" announces the Iguanodon.
