It is now generally accepted that the child's reading ability progresses through several periods of reading development. The first period, known as "reading readiness," begins at birth and continues normally until the age of about six or seven. Reading readiness includes the physical ability to see and hear, and the mental ability to remember words and their letters, and to use simple sentences.
In the second period of reading development, children learn to read very simple materials. In the United States, children usually will be able to read perhaps 300 or 400 words by the end of the first year. By the end of this period., pupils are expected to be reading and enjoying simple books by themselves without help from teachers or parents.
