Ordinal Numbers (1st to 20th)
Ordinal Numbers: Learn
When objects are placed in order, we use ordinal numbers to tell their position. Ordinal numbers are similar to the numbers that you learned before (they are called Cardinal numbers). If ten students ran a race, we would say that the student that ran the fastest was in first place, the next student was in second place, and then there would be third, fourth, fifth, sixth, seventh, eighth, ninth and tenth places.
The list on the left contains the first ten ordinal numbers, and the list on the right contains the next ten ordinal numbers.
