Before this lecture, I give students a strip of stickers with colored circles (you can buy them at Office Max/Depot. This gets them thinking about world poverty and why some countries are so wealthy while others are so poor. It also gets them moving around the classroom. They can place their stickers where they think they belong in a low-risk setting because no one will know which stickers belongs to whom. Each student places five stickers on one world map, this Survey 1, and the other attached document Survey 2.
