Part of the "Storyworlds" series, this pack contains the four Stage Four "Once-Upon-a-Time World" stories: "The Ant and the Dove", "The Sun and the Wind", "Little Rabbit" and "Town Mouse and Country Mouse". Each stage of "Storyworlds" provides a carefully structured introduction of words and language. The different worlds ensure that these are introduced and practised in a variety of contexts. Stages Four, Five and Six adopt a broadening structure to encourage the move to independent reading. Between 20 and 40 new words are added at each of these three stages, and continued repetition of text helps to maintain the build-up of confidence.
