A silly question probably. Our school uses ORT almost exclusively.
DS is doing fine with his reading, but I have noticed that if he's really interested in a story, and especially one aspect of it, after he's read an interesting sentence he will stare hard at the accompanying picture and this really seems to help his comprehension.
I think our school keeps them on the ORT books for a good long while and was wondering if at any level the pictures suddenly disappear? He does read other books at home without so many pictures, but the pictures do seem to help him. He's on Stage 11 (beige?) at the moment, if this helps.
