Great game!  Our whole family has been playing this game!  It forces kiddos to use problem solving to come up with the lowest score.  They have to use their memory to remember what they have and the other players have.  They also need to keep score and tally the total of their cards.  This would be great for students k-3 as a classroom center, or for homeschoolers.  We have only had this game a few months and already the cards are starting to show how much we love this game!
