Colección nivelado por grado can be used for guided and independent reading. These carefully leveled readers help children develop reading confidence and skills through a balanced sequence of increasing complexity, both in concepts and language use. Each title supports and encourages success of developing readers as they move from guided reading to higher levels of independent reading. A convenient library box, with tabbed Teacher Plan Cards for easy use and storage, is included. These cards are intended as guides for teachers looking for ideas and support in using the program effectively.
