                  ORDINaL NUMBERS

                  We use numbers to tell the
                  position of things.

                  Here, 10 animals are in a queue

                  to perform in the circus. Let us                    2nd         4th       6th        8th
                  have a look at the positions of                   (second)    (fourth)   (sixth)    (eighth)

                  these animals.

                  The numbers such as first,
                  second, third, ... which tell us

                  the position of an object in a
                                                                                                                     10th
