Teacher asks what do u observe with this, the students answers it as 6 is repeated twice.

Therefore the activity can be done with different number of beads and different group of students
Refer this link for the squares of the number https://www.youtube.com/watch?v=PycU-hi4rl0
Hence the teacher helps out the students with different number of beads where the students figures it out the repetition of numbers twice, with this the teacher ask the students what do we tell when the same number is repeated twice.

The teacher concludes that the repetition of the same number twice is called the ''square of the number'' which is also called as '''''perfect square'''''

In general, if we consider a natural number ''m'' can be expressed as n^2,where n is also a natural number, then m is a square number.
for example 7*7=7^2=49,therefore 1,4,9,16,25......... are perfect squares.
What about the numbers which comes in between the two square numbers?
If we see the numbers 5^2=25 and 6^2=36 there comes many natural numbers between 25 and 36 but we can notice that there is no natural number between 5 and 6 so,the numbers which comes in between two perfect squares or square numbers are called non perfect squares
