I was thinking along the same lines emile. Maybe you could have pile of flashcards/wordcards, one for each of the who, what etc. When a student picks up a card they have to substitute the card into the sentence. e.g. "park" - "That's where I hang out" or "steak" - That's what I eat.

Or maybe you could try saying items and having the kids yell out the sentences. e.g. T says "Steak" S says "That's what i eat."

I hope that helps...
