Where little heads lie down

Growing up, I always begged my mom to let me have my own room. In fact, several years in a row I wrote "My own room" on my Christmas list as something that I wanted. My mom worked out a great rotation to let each of her three daughters have their own room for a short while. While I thought that the solution, at the time, was mediocre, I know now how I should be quite thankful. A friend shared this link with me from the NY Times featuring photos of where children around the world sleep.

How could you use this to inspire discussions in your classroom? How could having students draw a picture of their bedrooms reveal something about their lives?
