              Objective: To reinforce the concept of formation of the greatest and

              the  smallest numbers and  finding  their  actual  and  estimated sums
              and differences.

              Materials required:  A dice, paper and pencil.
              Procedure:

                     Š Divide the class into groups of 5-6 students.

                     Š Invite the groups one by one to perform the activity.
                     Š Each member of a group should have his/her own dice.








































                     Š All members of the group will roll their dice together and note down the top
                      number (digits) of each dice.

                     Š The group will form the greatest and smallest 6-digit numbers using those digits.

                     Š Find the sum and difference of numbers obtained.
                     Š Also, find the estimated sum and difference of numbers obtained by rounding

                      off to the nearest suitable place.
                     Š Observe the difference between the actual and estimated sum or difference.

                     Š Repeat this activity with other groups till time permits.
