                  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.
