The Rhyme and Analogy series aims to support children's early rhyme and letter knowledge. Knowledge of commonly used rhymes can be used to recognize and read new words by the strategy of analogy. The story rhymes are built around a graded structure of rhyming words, with four clue rhymes being introduced in each story. The stories are lively and humorous and introduce the clue rhymes in a real reading context. They are supported by a teacher's guide and photocopiable resources, and are at the centre of the Rhyme and Analogy programme. Roderick Hunt is well known for his stories in the Oxford Reading Tree, and Dr Usha Goswami leads research in this field.
