Life the flaps, pull the tabs, turn the wheels--it's motorized fun in a book! Children love large vehicles! Presented here in sturdy books overflowing with both fun and solid information are two of children's favorite heavy machines--an airplane and a bulldozer. What better way to prepare children for a first plane ride than with a highly interactive and reassuing look at a jet plane? And how much more fun children will find viewing a construction site, knowing how a bulldozer works--from shovel to gearshift and dipstick to wheels. Using the interactive features in these books, children will gain an immediate understanding of the inner workings of these massive machines.
