As a middle school math teacher, I have fallen in love with individual white boards. What I haven't fallen in love with are the ineffective little erasers that the white board companies offer. After using two different types of erasers, I decided to try using a plain cotton sock as an eraser. It worked great! I have every child bring in an old pair of white athletic socks. About once a week, I take them home to wash them. They'll never be white again, but who cares? They work great!
