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.
