Memorize the rules of pluralizing nouns
There are many rules for converting singular nouns to plurals. This worksheet gives the student practice in pluralizing singular nouns, or the reverse, or both. You can select as many of the plural rules as you wish, and examples of those types will be used to fill the worksheet page. Naturally, some rules do not have very many examples in the English language, so you may want to select several types in order to have a full page.
