The number of words increases slightly in Green level books. Stories have a wider variety of characters and events which develop over a number of pages. Sentences may include lists of things or actions, and adverbs are used frequently to begin sentences. The books begin to use capital letters to support reading with expression. The growing complexity in the story lines is reinforced through the development of inference and prediction using visual literacy. All of the books introduce new sets of characters which are revisited throughout the level.
