What does Orton-Gillingham Reading instruction involve?

An Orton-Gillingham based reading lesson will often consist of several parts each focusing on a different skill. First, the student will review reading the sounds, prefixes, suffixes, roots that have been mastered. Second, the student spells about 8 of these sounds. Next, there is a phonemic awareness activity. Then the student reads 6-8 word lists with prior taught concepts, sight words and some nonsense words. Then the student says and spells words with several skills taught over the past few lessons. Then the student writes two sentences that are dictated to them. Then there is a lesson involving a new concept with explicit instruction and repeated practice of reading, spelling, and saying the new concept. Next, two sight words are taught. Last the student reads a text on their reading level.
