Prepare a table with the name of each player, as shown below.
In front of each name, there are boxes to make seven-digit numbers. Game 1 :
The first player throws the dice and writes that number in any one of the boxes in front of his/her name. You can write only one number in each box and once it is written, you cannot change its place. The other players do the same till all the boxes are filled and each one gets a seven-digit number. The one with the largest number is the winner.

Game 2 :
Use the same table, but you may write the number (you get on throwing the dice) in any box in front of anyone’s name. The one with the largest number is the winner.

Game 3 :
The rules are the same as for game 2, but the one with the smallest number is the winner.

Bigger and smaller numbers

Hamid : How do we determine the smaller or bigger number when we are dealing with six- or seven-digit numbers ?

Teacher : You have learnt how to do that with five-digit numbers. The number with the bigger ten thousands digit is the bigger number. If they are the same, we look at the thousands digits to determine the smaller or bigger number.

Now, can you tell how to compare six- or seven-digit numbers ? Hamid : Yes, I can. First, we’ll look at the ten lakhs digits. If they are the same, we’ll look at the digits in the lakhs place. If those are equal, we look at the ten thousands place to tell the smaller or bigger number and so on. Besides, we might be able to tell which of the numbers is bigger, just by looking at the number of digits in each number. Right ?

Teacher : Absolutely ! The number with more digits is the bigger number.
