I agree with you. Pre-K children come to us in at a wide range of levels. Some of my students know letter sounds; others don't know a letter from a scribble. The great thing about ZooPhonics is the children who know letter sounds see and understand them, and the children who don't have a clue about letters enjoy the animal characters. It reaches everyone at their level. If that's not DAP, I don't know what is.
