Phonics is the method of teaching English language by developing Phoneme awareness. It is the connection between graphemes (letter symbols) and Phonemes (letter sounds). Phonics is one of the primary building blocks of reading. Without an understanding between letter and sounds, reading cannot occur.
Right from childhood we have close association with sounds. Children are attracted to sound and replicate the same. The string of sounds form a word which in turn makes a sentence and all put together becomes a language.
Eg. (/b/ is buh) (/e/ is eh) (/d/is duh). Children learn the sounds of /b/, /e/, /d/ and blends the sounds (/buh-eh- duh/) to learn the word ‘bed’
