The books are aimed at children who can read a little, but who need lively but structured books to help them develop their skills further, focusing particularly on phonics. Using a familiar tale, the entertaining, rhyming text complements the child’s more formal learning.

A page at the beginning of each book helps adults to understand how best to use the book with the child. At the end of each book, a number of different activities reinforce the key sounds from the book. Activities include rhyming words, letter sounds, the way letters work together, key words, and a “retell the story” section.
