# Activity - UNION of sets

## Estimated Time :- 30 mins

## Materials required :-flash cards

## Prerequisites/Instructions, if any

## Multimedia resources

## Website interactives/ links/ simulations/ Geogebra Applets

## Process

- group 1 :- Ask the students to group the numbers which are multipliers of 3
- group 2 :- ask the students to group the even numbers.
- tell the group to write the numbers in set form.
- ask the students to observe the common numbers.
- write all the numbers sequently in the set form,
- NOTE : - IF ANY NUMBER IS REPEATED WRITE ONCE.

## Developmental Questions (What discussion questions)

what numbers are in both the sets ?

## Evaluation (Questions for assessment of the child)

- how many numbers are repeated ?
- how many numbers are not repeated ?
- how many numbers contain UNION SET ?

## Question Corner

- Write the union set for the following sets.

A = { a, b, c, d, e } B = { a, e, f, g, h }
