I love word games, Boggle is one of my favourites. As a TTOC, it's a fun game to do writing letters on the board, or having handouts. In a classroom long term, you can set up a bulletin board or station for this type of game.

Arrange letters on a wall (or a wall, desk, cabinet... I've seen some pretty nifty use of space with these!), embedding spelling words, sight words, vocabulary or "bonus" words for students to find using the same rules used to play Boggle. I love a comment on 4thGradeFrolics that suggested making one word using all the letters posted (related to something being taught in class or a seasonal concept) and challenging students to work on it when they have free time. You can change the letters at intervals and present a new challenge to students.Pinterest has more examples.
