ACTIVITY 1 :
1. Collect different kinds of objects. 2. Put the all objects in a box. 3. Calling 2 or 3 students and telling them to pick up things of same kind.
ACTIVITY 2:
1. Put the prepared number cards in another box.
2.Call a student and tell him to pick any 10 numbers.
3.Call a student and tell him to collect natural number
4. Similarly we can call many students to come and ask them to collect odd, even numbers etc.
DEVELOPING QUESTIONS:
1. Can you call that mixing group of objects by a particular name?
2. Does any number is repeated while collecting numbers?
3. What is the difference between before and after grouping the objects?
QUESTIONS:
1.Can we say that whole group of objects is a set ?
2..Define a set.
3. Give an example for a set.
