Decimal Card Game

I have found that my students can not practice decimals enough!  They are required to have a solid understanding of decimals in fifth grade so I try to spend some time practicing decimals with them.  This time I game each group of two (and one group of three) a deck of cards and a counter.  They used the counter as a decimal.  They each put down three cards-one to the left of the decimal (counter) and two to the right of the decimal.  They then compared each decimal.  The person who had the greatest number got all six cards.  The person who had all the cards (or the most cards) won the game.
