WH Questions- so many of my language delayed kiddos and my kiddos with Autism have difficulty discriminating this area of language (asking and answering what, when, where, why, who questions appropriately)
This is a very important skill and parents need to practice this at home with their kids everyday! Example: Its lunch time " where do we go to make lunch" "who makes lunch at our house" "when do we eat lunch" "what do we eat for lunch" I have found that a lot of kids will answer all four of these questions with the "what" answer. I use a lot of visuals when working on these skills.
Will post some great printables soon on my website for his purpose.
