How did you teach your son how to read?
He is hyperlexic. He has had a natural interest in letters and sounds since he was one and half. We started with letters and their sounds after we noticed that he memorized all of them on his own by age two. We moved on to CVC words next. He memorized a lot of words from books we read also. I taught him about silent e, diphthongs, digraphs and consonant blends over time, as he expressed he was ready. Make everything a game or song. Just have fun!
