Orthographic mapping

Orthographic mapping is the mental process of connecting each sound in a word to the letters that spell it, so the spelling is stored and the word is then recognized instantly.

Readers do not store words as pictures or shapes. Each time a student sounds out a word and links its sounds to its letters, the connection gets stronger, until the word is read at a glance. That is why it depends on phonemic awareness and letter-sound knowledge, and why those are taught first.

Why it matters for the record

A student who still sounds out a word they have read many times may need more work on the sounds inside it, not more repetitions of the word.
