Card Match
Play using half a pack of standard playing cards. Remove 2 of the 4 suits, so you have just 2 aces, 2 kings, 2 queens and so on.

Start by laying out 24 of the cards, making sure the 24 cards consists of 12 matched pairs. Once face down, move the cards around so that you do not know where any single card is located.

Turn one card over at a time, take a look at the number or object, and then turn it face down again. Repeat this process until you turn over a card that matches a card you turned over earlier. Now find the card’s ‘mate’ by remembering from earlier where it is located. As you find a matched pair, remove them from the group. The number of cards dwindles until all the pairs are matched.
