RWI Comprehension is the next step in developing children's composition and writing skills once they have become confident readers. Children work through the 30 weekly modules, specially written to link reading and writing activities to carefully levelled texts. Each of the 16 children's books listed have an accompanying module with activities which provide practice in reading, writing and spelling, and consolidate the pupils' knowledge through comprehension and guided composition. The illustrated children's books that accompany 16 of the Comprehension modules can all be purchased from Oxford University Press in the same way as the module packs.
