Welcome to Phoneme-Grapheme

A website dedicated to the development of automaticity and fluency with reading and spelling for all ages.

This site features ideas from professional developer, consultant, and author Kathryn Grace. Ms. Grace is best known as the originator of Phoneme-Grapheme Mapping (PGM) which she created in 1983 while teaching in her Vermont classroom.  Her Phoneme Grapheme mapping process has influenced countless literacy professionals and has been instrumental in helping students of all ages better understand the alphabetic principle, the knowledge that there are systematic and predictable relationships between written letters (graphemes) and spoken sounds (phonemes).

The sequential, systematic, and explicit lessons in her acclaimed and influential book, Phonics and Spelling Through Phoneme-Grapheme Mapping, are a direct outcome of her experience teaching young students and incorporate best practice based on empirical research. Its multisensory elements help to bridge the brain’s phonological and orthographic processors to strengthen learning and recall.
