                  Objective: To boost the understanding of subtraction of 2-digit numbers

                  with regrouping.

                  Materials required: Two dice, pen/pencil, eraser and notebook.

                  Procedure:

                          Divide the class into pairs.

                          Each student in the group
                          will roll a pair of dice and

                          note down the number of
                          dots (consider as digits) face

                          up.

                          He/she will form the greatest
                          2-digit number from those

                          digits and write it in the first
                          box.

                          He/she will form the smallest 2-digit number from those digits and write it in
                          the second box.

                          Then, he/she will subtract the numbers and write the answer in the last box.

                          Verify the answer calculated by your partner. If the answer is correct, the player

                          wins 1 point. If the answer is incorrect, the player loses the point.

                          The player that gets more points is the winner.
