              Objective: To reinforce the concept of multiples through a board game.

              Materials Required:  Game board,  a die and  counters of different
                                        colours.
              Preparation  of the  game board: The teacher  tell  the  students  to take a  sheet  of
              square grid paper and write any number from 1 to 100

              in the small squares, numbers can repeat.
              Procedure:

                     Š  The game can be played in pairs or groups of four.
                     Š  Each  player will  choose a specific  colour for her/his
                      counter.

                     Š  A player  rolls  the  die  and  according  to the  number
                      came on the die,  chooses to  opt to  place her/his            12    45    26   28    31    33
                      counter on any one  multiple  (on the board) of  that          5     24    15   42    25    35

                     Š  After 10-15 rounds,  the  player who has  the most
                      counters on the board is the winner.                           18    20    22   48    6     9
