Acorn is the new Heinemann Library brand for 2006. Each title is levelled for 4-6 year olds to build their confidence. Simple, patterned text and predictable page design helps to develop understanding of key issues and text is closely matched to the pictures. Each book in this series looks at one part of the body and explains what it is used for. Four new titles for 2007 look at Legs, Feet, Tails and Wings. Stunning photographs show how each body part differs across an amazing variety of the world's creatures. The book also includes comparisons with the human body, so readers can see each body part within a familiar context.
