Only the most important phonic rules should be taught in the least complicated manner possible. For example, in teaching vowel sounds, it is distracting to talk about "short versus long" vowels. Instead, a child should be taught the short vowel sounds first. Then when a child encounters a long vowel as in the word find, tell him, "That vowel says its own name."
Phonics must be taught in a way that allows these children to immediately practice phonic information in real stories. Every time a child is taught new phonic information, he should be given a short reading selection that highlights the phonic rule. Completing a skill sheet is good, but even better is to help the child practice applying the phonic skill to connected print
