extension problem example: In how many ways, can you use 1, 2, 3 to get
the target number of 6? In how many ways can 15 be written as the sum
of four different counting numbers?

**Guess My Number with minimum number of questions**

**Topics covered: Guess and check, multiples, logical reasoning**

One
of the students thinks of a 3 digit number and his or her opponent is
challenged to be able to guess the number correctly by asking minimum
number of questions. Only questions are allowed are of the following
kind about a particular digit (unit's digit, 10's digit or 100's digit):

Is the digit a multiple of x?

Is the digit x?

Is the digit a prime number?

Is the digit > x?

Guess My Unique Number From the clues I give

One
of the students thinks of a number and comes up with clues that would
allow the opponent to come with a solution. If opponent can't come up
with an answer, you get a point. If opponent shows that there is more
than one solution, he or she gets a point.

For example: I have a two digit number between 50 and 60. It is a multiple of 3. It is an even number. What number is it?

**Figure out my Encryption Code**

One of the two students uses Cryptogram code of shifting each
letter by certain places and representing it by its position to create a
sentence with 20 to 30 words and challenges the part to figure it out.
Take turns and see who can figure it out as fast as you can.

Next, create a code to represent each digit or some digits by letters.
Then, create a few sums or products using this code. Ask the other team
to figure out your code.

**Figure out my number**

One of the two students thinks of a number, then adds to a number to it,
multiplies it by another number, subtracts another number and tells the
product to the opponent. Opponent tries to guess the original number
by working backwards. Then, the students take turns.
