For example, phonics is a method for teaching reading and writing of the English language by developing learners' phonemic awareness—the ability to hear, identify, and manipulate phonemes—in order to teach the correspondence between these sounds and the spelling patterns (graphemes) that represent them.
Ex: Two letters that represent one speech sound. Examples: sh, ch, th, ph. Two letters that together make one vowel sound. Examples: ai, oo, ow.
