This document from a private school teacher discusses ordinal numbers, their uses in denoting the place or order of people or objects, and how they are formed from cardinal numbers. Ordinal numbers are formed either by adding "th" to the cardinal number or by adding the last two letters of the ordinal word to the number. Examples of ordinal numbers and their corresponding forms are provided.
