Since meeting the chickens and the fox in the first title of the popular series, The Chickens and the Fox, young readers have seen the sly fox try over and over to outwit the clever chickens. In The Trampoline, the fox uses a trampoline to try and bounce into the chicken yard. The chickens have to think fast to stop him! The Trampoline, part of the illustrated The Chickens and the Fox set, is an F leveled, Upper Emergent title.
