Teach your child about probability by playing a fun card game. This simple and fun card game is a helpful visual aid to help master an elusive math concept. Your child will have a better grasp on what the probability of winning is based on how many cards are used during the game.
What You Need:
- Deck of cards with the face cards (jacks, queens, and kings), tens and aces removed
What You Do:
- Place three cards on the table, face up. Together, you and your child should pick out four numbers to be the target numbers.
- Turn the cards face down and shuffle them thoroughly.
- Ask your kid to bet for, or against, you turning over a card that features one of his target numbers.
- Flip over four of the cards. Ask your child if any of the cards you flipped over feature a target number.
- If he bet that you'd turn a target number card over and you did, he earns two points. If he bet that you wouldn't turn over a target card and you didn't he earns one point. If he bet that you would turn over a target card and you didn't he loses a point, and if he bet that you wouldn't turn a target card over and you did, he loses 1 point.
- Play for an even number rounds, as you'd like, then tabulate the score. If his score is positive, he wins. If it's negative, you win.
- Does he think this is a good game to bet money on? If there was only 1 target number, instead of 4, what would happen to the probability of a given card being turned over?
- Try to work together to figure out a similar card game that would have about the same probability as the one just played.
