A good way of doing it is to write each ordinal number, either by word or by number, on a small slip of paper and hand them out randomly face down on the students desks . Bring in a stop watch, and tell them when you say go they have to get into a line from 1st to the highest number and then call them out correctly. Time it and then play again, telling them they have a chance to beat their previous time, though mix up the cards again.
Another way is to have a mini olympics in teams and award first, second, third etc.
