OH my goodness, someone used a permanent marker on the SMART Board. You’re angry and worried. Will it be there forever? Now you have a mission. Find a really smelly, dry erase marker. (Don’t be sniffing it in front of the kids!) Rub the dry erase marker over the permanent pen mark. Then use a soft cloth to erase them both. Next? Throw out any permanent markers in your class!
