Irregular plural nouns interactive worksheet - Free Printable

Let’s solve this step by step.

We are given 14 singular nouns that have irregular plurals — meaning they don’t just add “-s” or “-es” to become plural. We need to write the correct plural form for each, and then match them to the pictures (though since we’re not describing images, we’ll focus on getting the plurals right).

Here’s the list with their correct irregular plurals:

1. Man → Men
(Change ‘a’ to ‘e’)

2. Foot → Feet
(Vowel change: oo → ee)

3. Knife → Knives
(Change ‘f’ to ‘v’ and add ‘es’)

4. Woman → Women
(Change ‘o’ to ‘e’ — tricky one!)

5. Child → Children
(Add ‘ren’ — very irregular)

6. Sheep → Sheep
(Same in singular and plural — no change!)

7. Tooth → Teeth
(Vowel change: oo → ee)

8. Fish → Fish (or sometimes *fishes* if talking about different species, but usually *fish*)
→ For this worksheet, it’s likely Fish (same as singular) because the picture probably shows multiple fish of the same kind.

9. Person → People
(Completely different word!)

10. Mouse → Mice
(Change ‘ouse’ to ‘ice’)

11. Leaf → Leaves
(Change ‘f’ to ‘v’ and add ‘es’)

12. Wolf → Wolves
(Same rule: f → v + es)

13. Scarf → Scarves (or *scarfs* — both accepted, but *scarves* is more common in British English; worksheets often prefer *scarves*)
→ Let’s go with Scarves (following the f→v+es pattern like knife/wolf/leaf)

14. Goose → Geese
(Vowel change: oo → ee)

Now let’s double-check each one:

✔ Man → Men
✔ Foot → Feet
✔ Knife → Knives
✔ Woman → Women
✔ Child → Children
✔ Sheep → Sheep
✔ Tooth → Teeth
✔ Fish → Fish (standard for general use)
✔ Person → People
✔ Mouse → Mice
✔ Leaf → Leaves
✔ Wolf → Wolves
✔ Scarf → Scarves (most commonly taught in schools)
✔ Goose → Geese

All look correct!

1. Men
2. Feet

4. Women
5. Children
6. Sheep
