Content: Irregular Words and Orthographic Mapping

The words  below all have something in common…

Cough

Who

Once

 

None of them follow the common English pronunciation rules.

Words like these words are labeled

irregular words

because they have unusual patterns of pronunciation.

These words need to be taught through direct instruction reinforced by repetition.

Orthographic mapping

happens when a student’s brain immediately connects the complete spelling of a word to the word’s pronunciation and meaning. This is much simpler with the word “to” than it is with the word “though.” Students need extra help and attention to orthographically map irregular words, but the process is the same as for words that follow regular patterns of pronunciation.

To help with orthographic mapping, we use phoneme-grapheme correspondences (like we taught in the previous unit using Elkonin boxes). For words with irregular pronunciation, however, it’s especially important to draw attention to both the regular and irregular parts of the word and to always move from the sound to the symbol.
