Monster Machines Sound Book 

Children will explore monster machines including a bulldozer, tractor, big rig, monster truck and more with this colorful book featuring real photographs. Studies show that young learners find it easier to associate real-life monster machines to photographs than to illustrations. From a bulldozer to a monster truck, this exciting book teaches children all about big, powerful machines! Other books in the Photo Fun Fact Series include: Barnyard Babies, Rescue Ready, and Peek-A-Boo At The Zoo.
