Big Machines

(4) K-3 Eyewitness Readers series. A crane knocks down the wall of a factory, a bulldozer "pushes the rubble into a pile," and a digger empties the rubble into a dump truck. Next, an excavator, a concrete mixer, and a forklift are among the trucks that help with the building of a new park. In all, twelve big machines are featured in this easy-to-read text (with a picture word-list reinforcing certain words, e.g., rubble, blade). The crisp photos throughout make the color drawing of the completed park a letdown.
