Biff, Chip and Kipper Stories: Decode and Develop are exciting new titles in the Oxford Reading Tree series. The stories continue to provide storylines full of humour and drama, with familiar settings and characters. They also support children's transition from fully decodable readers, such as Floppy's Phonics, to a richer, wider reading experience with high-interest vocabulary.ooks contain inside cover notes to support children in their reading. Help with childrens reading development is also available at www.oxfordowl.co.uk.
