Double the dinosaurs / Murray, Diana

First there's one dinosaur, then two, then four... keep up the doubling and there will sixty-four dinosaurs before the story's through. The dinosaurs like to stomp and play, but they seem to keep multiplying. This math reader is a great introduction to the concept of addition and doubling.

In this story that introduces the fundamentals of addition and the concept of doubling, a swamp becomes quite crowded as the number of dinosaurs doubles each time, from one to sixty-four.
