A simple game to review vocab

I'll use this game once or twice a semester to either review vocab that we've studied in class that day, or to start off a new class to review stuff from the previous week.  I make a grid on my computer.  Maybe 4x5.  Then, I fill in the chart with half words and half definitions.  Examples from this week:
Exhausted/very tired. It's between my head and shoulders/neck. If I drink too much soju/stomachache.

Make a few copies and cut them out. Put the students in groups of 4 or 5 and have them put them face down on the desk.  They go around, one at a time trying to make a match.  If you make a match, you get to go again.
