So, students are supposed to write their name on the plastic name plaque using vis a vis markers. After the class, it should be a simple matter to wipe the names off with a paper towel and water. Except that, somehow, a Sharpie from the last class is placed in the vis a vis can and one of the students writes their name on the name plaque in permanent marker. Not a problem. I simply trace over the student's name with a dry erase marker and then erase everything. Works great! Problem solved! Problem 2: Instead of accidentally writing on the plastic name plaque with a permanent marker, this student writes his name with a dry erase marker. What do you mean you can use an erasable dry erase marker to remove a permanent marker from a plastic name plaque, but there's no way to erase the erasable dry erase marker unless the student had enough foresight to accidentally write on the plastic with an unerasable Sharpie before accidentally writing on the plastic with an erasable dry erase marker?!!! What the heck is up with that?!?!
