About these irregular plural nouns worksheets

Most nouns add -s or -es to mean more than one. Irregular plural nouns change in a special way: one child becomes two children, one tooth becomes two teeth, one mouse becomes two mice, and some nouns, like fish, sheep and deer, stay the same.

These irregular plural nouns worksheets start with a chart that groups the plurals by how they change. Practice pages ask children to write the plural, choose the right plural in a sentence, sort regular and irregular plurals (cut and paste or write), fix the wrong plural in a sentence, match singular to plural, and write their own sentences.

Every page with right answers has an answer key.
