I set up this activity for my adults elementary students. It is a perfect way to let them practice making offers and request in freer speach. By looking at the card they decide wether it is an offer, a request or a permission and put in the gaps "Can I...?", "Could/Can you?", "Would you like?". One by one the s-s ask questions and give possible answers. Present the respons on the board so they could have a visual choice of negative and positive replies. Enjoy the activity!
