What this sheet practices
Singular nouns are given and students write the irregular plural. These words do not simply take -s, so each one has to be learned as a pair.
Errors worth watching for
- Writing 'childs' or 'mouses'.
- Changing the vowel but adding -s as well (tooths).
How to use it
- Set the difficulty. Easy narrows the range; challenge adds missing values or extra steps.
- Choose how many questions and how many fit on a page. Ten per page is the most readable default.
- Print, or save as PDF. Replace any single question with the circular arrow if it does not fit your group.

Questions
About this generator
Why are some plurals the same as the singular?
Words such as fish, sheep and deer do not change. That is correct English, not an error.
How many pairs are included?
Twenty-four common irregular plurals.
Can I print this worksheet on A4 paper?
Yes. Switch Paper to A4 in the settings panel. The layout recalculates the page height and keeps 0.5-inch margins, so nothing is cut off.
Is an answer key included?
The generator always produces an answer key and worked solutions. They are part of the pass; the student sheet can be previewed and printed for free.
