In small groups, students will try to guess the word as the rest of their group acts out or "explains" the word without using the word or any part of the word.  The group acting it out will spin the wheel and record correct guesses.  The guesser will be facing the back of the device being used by the group and may pass as many times as desired.   A suggestion is to use a set amount of time after which all groups rotate guessers.
