Young children love big machines, whether they are tractors or trucks, or machines that work building homes or roads. Rough & Tough is an ideal new series for these children. Each book has rough, tough tire corners. Inside, the books are full of tactile elements, encouraging children to explore and think more about what each tractor or digger would look and feel like. Key facts relate each subject to the child's world. For example, a bulldozer weighs as much as 700 seven-year-old children, and a wheel loader's bucket can hold enough sand to make 6,000 sandcastles.
