If you can excuse the reproduction quality, here's an icebreaker idea you might use in the next couple of weeks. Design a page like this Christmas tree with several bingo items your students can sign off on. This will get them moving around the room and talking to everyone in an informal, holiday-like atmosphere. You can play for a winner (the first person who gets all the Christmas tree boxes signed) or just for fun. In either case, call on several volunteers to share remembrances of the occasions indicated by the boxes they signed.
