I have a Graffiti Day when it’s time to review a unit. Each student gets a dry erase marker, and they have ten minutes to graffiti-ize the room. The graffiti must be related to the given topic. They can only write on glass surfaces, white boards and desktops and only school appropriate language can be used. While we all browse and admire the graffiti, I ask questions and point out the important stuff. The kids have just as much fun erasing what they wrote when we’re finished.
