Divide students into two teams and give each student a number. Number 1 from each team comes to the front of the room. The teacher reads a clue related to a word (the clue could be a definition or example of the word) and the first person to slap the board or desk gets to answer. If correct, his team earns a point. If incorrect, the person from the other team has a chance to earn a point. Repeat with the following sets of students. The team with the most points wins.
