The "Storyworlds" scheme offers graded texts to ensure steady progression of reading skills in a highly supportive structure. The books may be used for guided, independent or take-home work. Each text is correlated to Book Bands. The "Storyworlds" genre-based approach is closely matched to the requirements of the NLS, English Language 5-14 and English in the Northern Ireland Curriculum. Stories from four "Worlds" - our world, fantasy world, once upon a time world and animal world - provide a range of settings, as recommended in each curriculum. Further coverage is provided by guided reading cards, which provide key teaching objectives for every title, and in the teaching guides.
