After the English reading student learns the short vowel sounds and the long vowel rule, the student should be introduced to the concept of digraphs. There are vowel digraphs, and there are consonant digraphs.
The vowel digraphs, for the most part follow the long vowel rule. For example, ‘ea’ and ‘ee’ usually indicate the long e sound. ‘Oa’ says the long o sound, and ‘ue’ usually indicates the long u sound. Additionally, ‘ie’ sometimes says the long i sound, as in the word ‘pie’, but it can also say the long e sound as in the words ‘piece’ and ‘niece’.
There are also consonant digraphs that change the sound of the consonant, such as, ‘ch’ ,’gh’, ‘ph’, ‘sh’, and ‘th’. example words of all of these can be taught as sight words: such, much, tough, rough, graph, phone, she, shell, the, and thing.
