In the game of “Concentration”, half the cards have a word we are studying and the other half have a definition of that term.  The cards are turned upside down, and a grid (like a Street directory) is added.  Students take turns to call out two cards.  If these match, they are kept.  If not, they are turned back over and it is the next person’s turn.  We have been playing the game in teams.  This helps with speaking and listening as well.
