1. The mysterious count- trick
2. Match stick count – odd or even game
3. opposite face of the dice
Slide2
Take a watch and ask someone to think of one of the hours on the dial
then you take a pencil and start tapping the various hours on the dial.
The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.
When his count reaches 21 he should shout stop.
Now I will tell the hour which he is thinking of.
Slide 3
Take a watch and ask someone to think of one of the hours on the dial -- 8
then you take a pencil and start tapping the various hours on the dial.
The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.
When his count reaches 21 he should shout stop.
Now I will tell the hour which he is thinking of
It is 8
Slide4
Take a watch and ask someone to think of one of the hours on the dial -- 8
then you take a pencil and start tapping the various hours on the dial.
The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.
When his count reaches 21 he should shout stop.
Now I will tell the hour which he is thinking of
It is 8
Slide5
Take a watch and ask someone to think of one of the hours on the dial -- 5
then you take a pencil and start tapping the various hours on the dial.
The person who is thinking of the hour should count the number of taps starting next from the (number) or hour he is thinking of.
When his count reaches 21 he should shout stop.
Now I will tell the hour which he is thinking of
It is 5
Slide6
First 8 taps any random order
but the 9th tap should fall on the hour 12
10th tap should fall on the hour 11
11th tap should fall on the hour 10 in an anti-clockwise
When he says stop -- He thought the hour of
If he thinks 12 then 12 + 9th tap you will get answer
If he thinks 11 then 11 + 10th tap
If he thinks 10, then 10 + 11th
If he thinks 9 then 9 + 12th tap
If he thinks 8 then 8 + 13th tap
If he thinks 7, then 7 + 14th tap you will get answer
If he thinks 6 then 6 + 15th tap
If he thinks 5 then 5 + 16th tap
If he thinks 4, then 4 + 17th tap you will get answer
If he thinks 3 then 3 + 18th tap
If he thinks 2 then 2 + 19th tap
If he thinks 1, then 1 + 20th tap you will get answer
Slide7
Take 20 match boxes.
You take few match sticks ask another to take few match sticks
If he has taken odd number of match, add your match sticks that total come to an even number.
If he has taken even number of match, add your match sticks that total come to an odd number.
Play a game & enjoy
Slide8
Your friends match stick count is odd so to make even how much you are going to give to him?
That is
5 + 1 = 6 (even);
5 + 2 = 7 (odd);
5 + 3 = 8 (even)
5 + 4 = 9 ( odd);
5 + 5 = 10 ( even)
Now you take some Match sticks Ask your friend to make compensate with his match sticks.
Carry on to play the game and learn Odd & Even numbers
conclusion
Odd + odd = even
Odd + even = odd
Slide 9
Dice are special number cubes for which the following rule applies:
You can make a simple number cube by cutting, folding and gluing Card board.
This can be done in many ways.
In the figure below you can see
four cuttings that can be used to make cubes, with dots on the sides.
Which of the following shapes can be folded together to form a cube that obeys the rule that the sum of opposite faces is 7?
Note :
The total number of dots on two opposite faces is always seven
Slide 10
Which of the following shapes can be folded together to form a cube that obeys the rule that the sum of opposite faces is 7?
Note :
The total number of dots on two opposite faces is always seven
Answer :
ii & iii only satisfies the rule {1+6; 2+5;3+4}
Play with your Friends Kutties! 👍
All the best!
Thank You🙏🏻
