GROUP ACTIVITY

To reinforce the concept of forming the smallest and the greatest 5-digit numbers and
understand subtraction of 5-digit numbers
Things We Need: White sheets of paper and a pencil

How To Do:

1. Divide the class into groups of 5.
2. Every child of each group will write a digit of his/her own choice. So, each group will
have 5 digits.

3. From the digits obtained, each group will form the greatest and the smallest 5-digit
numbers and find the difference between them.
