we showed this card trick to a group of middle schoolers, they gasped
in amazementand all wanted to learn how to do it.
With A group
instructions will help you lead your group through learning the
Mind Reader card trick. Don't worry if you are a klutz with cards.
This trick requires no manual dexterity (though having a little
mental dexterity helps).
Demonstrating the Trick
Read over the Mind Reader
instructions and try the trick a few times. Once you are confident
that you can do the trick, demonstrate it to your group.
First, ask everyone
to get out a pencil and paper so that they can write down the answers
to the mathematical questions youll be asking. Turn your back
while the group selects a card and lays it on a table or desk. Then
chose a card yourself, memorize it, and put it down just to the
right of the card the group has chosen.
the steps on Mind Reader instructions.
Have the group follow your directions. When they have reached the
end of the calculations, turn over the cards and reveal the number
that they have calculated.

to point out to people that the magician doesnt actually know
the number thats in the other persons head until the
cards are turned over. The magician only knows the card he or she

result of the persons mathematical calculations. If the person
came up with a different number, then the magician and the person
should check the math together. If the math is done correctly, the
number will match the cards.
Figuring Out How the Trick Works
number has two places: the 10s place and the 1s place.

place, which means there are two 10s, and theres a 5
in the 1s place, which means there are five 1s.
In this trick,
the magician gets the person being tricked to do a series of mathematical
operations that move the number of the persons card from the
1s place to the 10s placeand puts the number of
the magicians card in the 1s place.
Mind Reader explains exactly how this happens. Younger middle
schoolers may not be able to follow the entire explanation, but
they may be able to see that the card the victim chooses always
