The Oxford Reading Tree scheme is designed to develop literacy skills in readers aged 3 and over. Featuring Biff, Chip, and Kipper, the 33 books cover reading levels 1 - 3 with words that support the illustrations. They introduce phonics, everyday language and common words, and encourage parents and children to enjoy storytime together. Titles include Super Dad, A Yak at the Picnic and The Red Hen.
