This is to read aloud, because it is all about the sound and shape of words. You can read it to children who can't read yet. They will hear some of the Os and see others on the page. They will have a sense that they are missing something, but that is all to the good: they will want to read when the time comes. In the meantime, pirates, men in black cloaks, treasure maps, and the final intervention of word spirits will keep them happy.
