Shuffle the deck of cards thoroughly.
Arrange the playing cards face down in even rows.
Choose the order the two players will take their turns with the youngest player taking her turn first.
Turn over two cards, exposing the pictures to all players and stating the name of the picture on the cards. If the two cards match, the player keeps the cards and takes another turn. Otherwise, the next player gets to take his turn.
Continue taking turns choosing two cards at a time and setting aside matches until all the cards are matched.
Declare the player with the most matching cards the winner or just celebrate completing all the matches for a more cooperative game.
Shuffle the cards and lay them out on the table to play again, adding more pairs of cards if your preschooler needs more of a challenge.
