The Phonics Handbook is the core of the Jolly Phonics program. The program is very organized, systematic, and fun for kids. Jolly Phonics was developed by a teacher in England and its use has spread to other English-speaking countries. It was part of several studies that demonstrated its incredible effectiveness, including, I believe the Clackmannanshire study (google that for convincing reason to teach your children via phonics). The teacher or parent starts by teaching the child 5 sounds and their corresponding letters. Within a week or two the child learns to blend those sounds together when reading words! All 44 English sounds (phonemes) are covered, along with their most common spellings. Writing is included, because spelling and reading go hand-in-hand. Highly recommended, as are Jolly Phonics' other resources.
