 Sight words were introduced after Whole language (a similar method) fell out of favor with the education establishment.Sight words account for a large percentage (up to 75%) of the words used in beginning children's print materials.The advantage for children being able to recognize sight words automatically is that a beginning reader will be able to identify the majority of words in a beginning text before they even attempt to read it; therefore, allowing the child to concentrate on meaning and comprehension as they read without having to stop and decode every single word.
