GROUP ACTIVITY

To reinforce the concept of forming the smallest and the greatest 4-digit numbers
using the given digits and check the understanding of number names

Things We Need: White sheets of paper and a pencil
How To Do:

1. Make 10 slips of paper. Write digits 0 to 9 on them, one digit on each slip. Fold
the slips and shuffle them.

2. Divide the class into groups of 4–5 children.

3. A child from a group will come and pick 4 slips. The child will unfold the slips
and write the digits obtained.

4. From the digits obtained, the group will form the greatest and the smallest
4-digit numbers and write their number names.

5. Repeat the same activity with each group.
