## Blackboard _vs._ whiteboard A [_blackboard_](http://en.wikipedia.org/wiki/Blackboard), also called a _chalkboard_, is usually black or dark green and is meant to be written on using chalk.  A [_whiteboard_](http://en.wikipedia.org/wiki/Whiteboard) is a smooth white plastic-coated board, meant to be written on using a felt pen.  Blackboards and whiteboards are different things. Whiteboards are starting to displace blackboards due to chalk allergies, among other reasons. However, referring to a blackboard as a "whiteboard" due to racial sensitivity is silly political correctness gone wild. If you really need a euphemism, call it a _chalkboard_.
