Demonstrate the rules in front of the class.
In Triple Concentration, you take turns with a partner to try to turn up a triple match. If you do not get a triple match (like the example below), it’s the end of your turn. Return the cards to the face down position on your desk. If you find a triple match, you get an extra turn.
The cards all have two metric values and something being measured that might match that value.
Instruct players to not rearrange the cards so they can memorize the locations and the information on the cards. Remind your students this game isn't about winning, but thinking about units. They should not bend the rules to make it easier to win the game.
Arranging the cards so you can memorize the locations and the information on the cards is against the rules and the spirit of the game. Mix the cards up well before you start turning them over.
