Sound Foundations
Early Childhood Education

Sound Foundations was found to have potentially positive effects on phonological processing and early reading/writing.

Sound Foundations, a literacy curriculum designed to teach phonological awareness to preliterate children, focuses exclusively on phoneme identity (that is, different words can start and end with the same sound). It works from the principle that phonemic awareness is necessary but not sufficient to reading. The curriculum is self-contained and can be used by teachers, parents, or teaching assistants.
