How do I teach irregular plural nouns?
Make a class chart of special plurals and add to it whenever one turns up in a book. Saying the pair out loud (one goose, two geese) helps it stick.
What mistake should I watch for?
Adding -s to an irregular noun, as in "mouses" or "foots". Ask, "Does that sound right?" Most children hear the correct form once they say it aloud.
