Here is a practice Powerpoint and a matching game, I stole the template from some other teacher and changed the pictures.
Practice key expressions: I'm hungry. I'm thirsty. Do you want some more?
For the matching game students choose two cards. If there is no match I point at a card and students say "Do you want some more ______?" No, thanks. The group gets one point if they say the answer together. If there is a match they say, "Do you want some more ______?" Yes, please. If they say together in the group they get 2 points for a match. Enjoy!
