My students looooooove learning about Don Quixote. They love his antics and all the trouble that he gets himself into.
When we are learning about Don Quixote, I print out Pablo Picasso's sketch of Don Quixote, Rocinante, and Sancho Panza. I end up putting one or two pieces of magnetic tape on the back of it. The kids then have this hanging in their lockers or they end up taking it home to put on their refrigerator.
