Children learn to read in a variety of ways: through formal teaching in school, being read aloud to at home, and reading on their own,using all the tools they’ve learned for making sense of letters and words. The process starts with a child’s first awareness that letters on the page form words, which make sentences, which make stories.No one method of learning is right for every child, but all children need books they can read successfully.

Ready-to-Read books feature classic stories and interesting nonfiction by authors who really know how to write for this age group. They’re grouped at three levels: Level 1, with repetitive, predictable text for children who are just starting to read; Level 2, for those who can read with help and are ready for slightly greater challenges; and Level 3, for children who can read fiction and nonfiction on their own, with fewer illustrations and longer texts. At each level,the books are all written, designed, and illustrated to suit the interests, needs, and abilities of new readers.

Children in preschool and the early elementary grades are universally fascinated with reading, and are already saying, "I’m ready to read." When they finish a Ready-to-Read book, we want them to say, "I am reading, and I like it!"
