Learning Digraphs th, wh, ch, sh

Consonant digraphs refer to a joint set of consonants that form one sound.  Common consonant digraphs include “sh”, “ch”, “wh” and “th”. Some digraphs are found at both the beginning and the end of a word. Others are strictly initial consonant digraphs, like “kn”, or final consonant digraphs, like “-ck”. The concept of consonant digraphs is often introduced in kindergarten and later expanded upon in first and second grade.
