Pair Up

Copy onto cards the percents and decimals shown below, one per card. Shuffle the cards and place them face down in rows of four.

On his or her turn, one partner flips over two cards at a time. If the two cards name the same number, they are removed from the game and this partner repeats the procedure. If the two cards do not name the same number, they are returned to the game face down, and it becomes the other partner's turn.

Continue in this way until all the cards have been removed. The player who removed more matching cards from the game is the winner.
