Chick and Robin are hungry. But who will get the worm? Reading Corner covers three grades of early reading ability. Compiled in consultation with Dr. Barrie Wade, Emeritus Professor of English in Education at the University of Birmingham, and Dr. Hilary Minns, Lecturer in English at the Institute of Education, University of Warwick. Each grade has three levels, indicated by the number of bars on the spine of the book. Each level has a limited number of words per story, to help you choose the right book for a young reader.
