@Sophie he’s home educated x
Can he continue a rhyming string eg if you say cat, hat could he think of other words such as bat, mat, chat? Can he orally blend eg “put on your c-oa-t” “can you get your c-u-p” as these things are good precursors of being able to blend. Feel free to message me x
Have you asked the school for advice? They probably have strategies that they use and it would help to all be using the same ones 😊
