Irregular Plural Nouns for Kids: Mice, Teeth, Children and Sheep (Grade 3 English)

Hi, I'm Luna from DoodleBeez. Today we are learning about irregular plural nouns. Most nouns just add s to show more than one. But some nouns break the rules and change in surprising ways.

Some nouns change the vowels in the middle. One tooth, two teeth. One foot, two feet. One goose, a flock of geese. We do not add s at all. We say teeth, not tooths.

Here are more vowel changers. One man, two men. One woman, two women. One mouse, two mice. Listen carefully, because the word sounds different when there is more than one.

A few nouns add e n or r e n. One child, two children. One ox, two oxen. And one person becomes people, which is a totally new word.

Some nouns stay exactly the same. One sheep, ten sheep. One deer, five deer. One moose, two moose. We use other words in the sentence, like numbers, to know if there is more than one.

Many nouns that end in f or f e change the f to v, then add e s. One leaf, many leaves. One knife, two knives. One wolf, a pack of wolves.

Now it's your turn. What are the plurals of foot, child and sheep? Pause and try. One foot, two feet. One child, many children. And one sheep, many sheep, because sheep stays the same.

Great job! Remember, irregular plurals do not just add s. Some change their vowels, some add e n, some stay the same, and some change f to v. Practice irregular plurals in the English Lab at doodlebeez.com. See you next time!
