Flipchart sheets and markers (be sure to have markers so that the writing is bright and visible). At the meeting you simply say, “We're going to have a poncho exercise, come to the flip chart and pick up a sheet.” Don't immediately explain what you're going to do - the intrigue adds interest. Then - everything is simple: fold the sheet in half, then again in half, cut a hole for the head - and the poncho is ready! Everyone puts on their ponchos and starts walking freely around the room. Now the most important thing is to take markers and ask everyone to write something on the poncho that they are grateful to each of their coworkers for. If someone doesn't know someone very well, you can simply write “Thank you for your kind smile” or “Thank you for always being supportive.” If you know them better - the thank you can be more specific.
