Riley has a dump truck, a flatbed truck, a concrete mixer, and a little pickup truck at his lumberyard. When he tells them that they will help him build a children's park, everyone is excited. There's a lot of hard work to do, from hauling trash to pouring concrete. But once the work gets started, everyone but Little Yellow Truck is busy. Is there nothing he can do to help? As it turns out, Riley has just the right task for Little Yellow Truck. This picture-book offering from author Eve Bunting reinforces the message that even the smallest helper can make a big impact.
