What's happening? At The Zoo Children's book. This delightful series, compiled with the help of experts, is designed to amuse young children and stimulate them to talk, to encourage them to learn new words and to distinguish visual differences. The detailed illustrations provide lots of incidents to talk about, things to find and things to count; there is also something really out of place as well as a yellow duck to find in each large picture. The questions on each page are there only to suggest starting points for conversations between the very young and parents, older children or teachers.
