From diggers to loaders, learn how these big building machines work and why we use them. A final review page helps test children's learning in a fun way.
This simple book uses cartoon-ish diagrams and simple text to describe what makes up a helicopter, and how it flies. My son is 7 years old, and he had no trouble understanding the concepts presented in the book. There were some words that gave him problems, like fuselage, but I like books that push his skills. This is a very good book.
