Preparing for a Contest - 2004
HCTM 2011
Conference - Math in Magic, Balloons &
Kites

This session will focus on utilizing a variety of teaching and learning strategies in integrating across the curriculum utilizing magic and balloons and other activities as the vehicles to support the classroom teachers' program
Objective:
This session will enable teachers to:
1. explore a variety of applications which can be used to help deliver
and/or support instruction,
2. design activities which uses magic and balloons and other
instructional medium to deliver and/or support instruction.
A variety of standards can be applied. Visit the various state standards. Here are some state standard starting points.
Pick a number between 5 & 15:
Pick a number from 1 through 12:
Close - Up
Mental
Parlor
Stage
Illusion
Engineers' tools: Math, science, and computers.
Actors' tools: Dress, play script, and stage props.
Chefs' tools: Food, spices, oven, and kitchen utensils
Singers' tools: Song and music.
Magicians' tools:
Cards, Money, Rope, Silk & Handkerchief, Sponge balls, Numbers & Math, etc.
Props (big & small)
Sleight of Hand
Magic Rules:
Never explain how a trick is done
Never explain what you are going to do ahead of time
Never repeat a trick for the same spectators
Practice each trick before you present it

Mind Reader ... an animal?
Patterns / Symmetry / Tessellations

Performance: Secret
Number
1.Write a 3-digit number with all different digits
2.Reverse the digits and subtract the smaller from the larger
3.Reverse the result and add them up
4.Answer should be
secret
number
Tear 3 pieces of paper and draw a circle on the first piece, a square
on the 2nd piece,
and a triangle on the 3rd piece.
Number each piece 1, 2 and 3 respectively by placing the
"1" in the circle
"2" in the square
"3" in the triangle

1) Circle, 2) Square, 3) Triangle
Opposite side write :
"4" on the back of the circle
"5" on back of the square
"6" on back of the triangle
Arrange the paper with 4, 5, 6 side up ...
mix them up to form any 3-digit number: 456, 654, 564,645, etc.
Take center paper and
turn it over ...
add up the 3 numbers ....
you have come up with a
number between 1 & 15
Think of a 2 digit number between 1 & 50
Both digits are odd
Both digits are different
Sum of digits greater than 9
Performance: Four-Ace Trick
1.Before trick, put 4 aces in positions 9, 10, 11, and 12 in deck.
2.Have subject pick a number between 10 and 20.
3.Deal that many off the deck.
4.Add digits of that number and put that many back on top of deck.
5.Take top card and set aside.
6.Repeat until you have four cards out of the deck.
7.These four cards will be the
aces.
Performance: Success
1. Before trick, prepare 4 cards faced up as follows:
Card 1(bottom and facing up): Teacher; Card 2: Success; Card 3: Collaboration; Card 4 (top and facing up): Learning.
2. Have subject flip the top "Learning" card.
3. Cut the deck.
4. Flip the top 2 cards.
5. Cut the deck.
6. Turn over all cards.
7. Flip the top 2 cards.
8. Cut the deck.
(May repeat steps 7 & 8)
9. Flip the top card.
10. Flip the top 2 cards as one.
11. Flip the top 3 cards as one.
12. You will note that 3 cards are faced one way and only one card is faced the other. Check the other participants, and it should be a "success!"
Performance: A Magician Kelvin Chun:
1.Have someone cut the deck approximately in half.
2.Pick up either half and count the number of cards.
3.Add the digits, and counting from the bottom, go to that card number.
Have subject remember the card.
4.Replace that 1/2 deck on top of the other half deck.
5.Spell out A M A G I C I A N K E L V I N C H U N

(or any other 19 letter phrase or
word)
Paper Magic:
Take paper and fill in the following letters:

Fold in 1/2
Fold in 1/2 again => 2 more times
You should have 8 separate rectangles
Trim off the edges of folded paper
Sort paper with face up and face down letters
Choose either one
Study letters and try to form a word with all the letters
If you can't make up a word, then choose other stack.
Secret Word?
Performance: Professor's NightMare
Performer shows three separate pieces of rope each of a different size.
There is a very short piece, a medium size piece, and a long piece. The
performer folds the three pieces and when the ropes are opened out again,
all three pieces are seen to be of the same size. A perfect illusion. If
required, the ropes can again be restored to their original different
sizes and tossed out for examination.
