2nd grade irregular plural nouns worksheets
Most plurals add -s, but a stubborn set of old words changes instead: mouse/mice, foot/feet, tooth/teeth, child/children, man/men, woman/women, goose/geese. Second graders learn this core set by meeting the words in sentences where the number cue makes the plural unmistakable.

How to teach this
These words are survivors from very old English, which is a fun fact that helps kids forgive them for breaking the rules. Teach the core seven or eight as sight vocabulary, with pictures and counting: one foot, two feet, one child, three children. Saying the wrong form out loud (two mouses!) usually earns a giggle and cements the right one.
Watch for: Some plurals don't change at all: one sheep, five sheep; one deer, three deer. The number word does all the work. Double-marked forms like mices or feets are never right; the changed word is already plural.
Common questions about irregular plural nouns
- Which irregular plurals should a 2nd grader know?
- The everyday set: mice, feet, teeth, children, men, women, and geese. These cover nearly every irregular plural a 2nd grader will read or write. Fish and sheep, which stay the same, round out the list nicely once the changing words are solid.
- My child writes "foots" and "childs." Should I correct it?
- Gently, and without worry; it's the same healthy overgeneralizing that produces "goed" and "runned." The child has learned the add-s rule and simply applies it everywhere. Practice with the real forms, plus hearing the wrong ones aloud, sorts it out over a few weeks.
