Daniel and I have had this game for years and we still love it. It's fun for kids and grown ups. The cards are numbered 1 through 60. Each person gets 10 cards and has to swap out one card at a time to get their numbers in order from lowest to highest. You can find the game online and in almost any store like wal-mart or Target. Or you can make your own version by following the directions on this website: Homemade Racko
We played with Daniel's parents this weekend. I lost repeatedly and badly. It was still fun. And when the kids play it counts towards math for the day in their homeschool records.
