I am a hearing father with a deaf son. My son is struggling with reading and I am struggling with how best to teach him to read. I was hoping that people here could give me some advice or recommendations on how to approach this. Are there any tools available (like flash cards or books that show a word with a picture of ASL handshapes/motions) or any methods that people have found that work effectively? Thanks in advance.
