So you want to be a math magician eh... Just one more reason that math is cool....Math Card Tricks! The thing about these tricks is they work because of math. Yes, they are fun to perform. But guess what...
Math card tricks are a learning tool for demonstrating and understanding different math concepts.
Children have always been fascinated by activities that involve magic tricks, and many can be performed using a pack of ordinary playing cards.
Multiplication Math Magic: Impress your child with math's magical powers with a card trick that uses math to do "magic". With this cool math card trick, you'll force any card to come out of the deck on your command!
If it is a two through nine card, place it face up, and count out cards up to the number ten. For instance, if you turn up a six, you would place it face up, and then count out four cards coming down, saying "Seven, eight, nine, ten." If you turned up a three, then seven cards, saying "Four, five, six, seven, eight, nine, ten."
If the card you turn up is an ace, ten, or picture, tell your friend that you must have cards 2 through nine for this trick and place the card on the bottom of the deck, face down like the rest of the cards. (Someone told me that aces and pictures work too, but I haven't verified it yet.)
Say the total was 23. Counting from the very top of the set-aside-pile-plus-remainder-cards, state you are interested in the 23rd card. Just before turning over the 23rd card, state what card it is!! (It is the 17th card that you memorized at the beginning of the trick!)
If you did everything correctly, it works every time! Amazing!
And even though these problems may appear to be recreational or magical in nature but they are actually based on sound mathematical concepts.
Kids can get a lot of enjoyment out of amazing friends and family performing math card tricks. It just takes a little practice to master the tricks so that you're comfortable doing them in front of an audience of one, ten, or a hundred. O.K., I guess I'm getting a little ahead of myself.
