                                       You will need: integer cards from -13 to 10.
                                       Instructions:
                                       O  Mix up the cards and place them face down in a stack.
                                       ©  Each player takes turns to draw 4 cards from the stack.
                                       ©  Both players will flip up their cards and arrange them from the smallest
                                           number on the left, to the greatest number on the right.
                                       o   Once done,  each  learner will check the order of the other learner's
                                           arrangement. The learner with the correct arrangement gets one point.
                                           If both arrangements are correct, the fastest learner gets one point.
                                       0   Continue doing this until all the cards have been  picked.
