A counting story that goes wrong when one hungry little T-Rex can't help himself from gobbling up the other dinosaurs! Let's count dinosaurs! Rex the T-Rex is 1. Add Patty the Diplodocus, that's 2. And here's comes Brian the Anklyosaurus to make 3. But wait, where's Brian gone? Rex? Rex! You didn't EAT him, did you? Oh NAUGHTY Rex! The truth is, you just CAN'T count on dinosaurs. In this counting book with a difference, Philip Ardagh and Elissa Elwick bring prehistoric chaos and trouble-making dinosaurs to every page for a truly fun, interactive way to learn how to count to 10.
