Since I have started working at my High School in North Philadelphia I have fallen in love with my whiteboard. I like to buy lots of colorful expo markers and make my board not just a place for information, but a fun place for information! There is also a projector mounted above my board so when I do elaborate designs I always have to keep in mind space for the projection or be OK with wiping it all away the next day. It seems my fascination with my whiteboard is contagious because now I often have students stopping by after school to hang out and just doodle. They seem more open to explore given the impermanent nature of the medium.
