Saxon Phonics is a success-oriented series that enables most children in a heterogeneous class to develop a solid foundation in phonics and thus become successful readers and spellers. In keeping with the Saxon philosophy, the phonics series builds on prior learning. New learning is presented in increments, and each increment is reviewed throughout the year, providing every child with the exposure needed to achieve success. Phonics is a method of teaching beginners how to read and spell by teaching them the sounds each letter or letter cluster makes and the rules governing the use of those sounds. Only after this understanding of the sound/letter relationship is achieved can successful, independent reading occur. A controlled reading and spelling vocabulary is used throughout Saxon Phonics and Spelling so that children are exposed only to words containing those letters, letter clusters, and sounds that have been taught. This ensures that children will experience continued success as they learn to read and spell.
