Turn your child into a little math-a-magician in no time! This impressive math card trick uses addition and multiplication. Your little one will easily memorize the secrets behind the trick and be able to wow his friends.
What You Need:
- Deck of cards
What You Do:
- Ask your child to shuffle the deck of cards. Tell him that for the purposes of the game aces = 1.
- Have him look at the bottom card and memorize it.
- Tell him to place the deck on the center of the table and turn over the top 3 cards.
- Now, have him deal cards below each of the 3 cards he turned over. He'll need to figure out how many cards to place down. To do this, have him subtract the number amount on the face up card from 15. For example: If the card is 5, he should deal 10 cards under it. 15 - 5 = 10.
- Now have him collect all cards he dealt in step 4, and put them on the bottom of the deck. The three original face-up cards should remain on the table.
- Ask him to find the sum of the three face-up cards and deal out that many cards. For example: If the 3 face-up cards are 2, Ace, and 5, he perform this addition operation 2 + 1 + 5 = 8.
- Then, place those cards on the bottom of the deck.
- Time for the magic! Explain that you can force any card to come out of the deck whenever you like. Now, ask him to name the card he chose in step 1.
- Wave your hand over the deck of cards mysteriously. Ask for his card to come forth! Encourage your little one repeat the command with a sly smile.
- Have him turn over the cards one by one on the top of the deck. At first, he won't see anything special. However, have him keep turning slowly as you say, "This is the first card, here's the second, this one's the third, and the (name of his card), comes fourth!" The fourth card will be his card!
- How did you do that? Explain to him that each face up card is equal to the amount of the card subtracted from 15, plus the value of the card = 16. Multiply 16 x 3 and you get 48. And, 48 + 4 = 52. There are 52 cards in a deck!
