Educational worksheet focusing on irregular plural nouns, featuring images and their plural forms for language learning.

Let’s go step by step through each pair of images to find the singular and plural forms of the irregular nouns.

We’ll look at each numbered box:

1 → One goose
2 → Three geese (plural of goose is geese)
→ So: goose / geese

3 → One knife
4 → Two knives (knife becomes knives — change “f” to “v” and add “es”)
→ So: knife / knives

5 → One man
6 → Two men (man becomes men — vowel change)
→ So: man / men

7 → One leaf? Wait — actually, image 7 shows a fern frond. But in English, we usually say “fern” for the plant, and “ferns” for multiple. But that’s regular. Hmm… wait — maybe it’s “leaf”? Image 8 shows two leaves? Let’s check:

Actually, looking again:
Image 7: one large fern leaf (frond)
Image 8: two smaller fern leaves? Or maybe it’s meant to be “leaf” and “leaves”? That makes sense — because “leaf” → “leaves” is irregular.

But let’s confirm with standard irregular plurals taught at this level.

Common ones:
- foot → feet
- tooth → teeth
- child → children
- mouse → mice
- person → people
- ox → oxen
- deer → deer (same!)
- sheep → sheep (same!)
- fish → fish or fishes (but often same)
- wolf → wolves
- life → lives
- half → halves
- shelf → shelves
- calf → calves
- elf → elves
- self → selves
- thief → thieves
- loaf → loaves
- sheaf → sheaves
- hoof → hooves or hoofs
- scarf → scarves or scarfs
- dwarf → dwarves or dwarfs
- wharf → wharves or wharfs
- staff → staves or staffs
- stratum → strata
- datum → data
- criterion → criteria
- phenomenon → phenomena
- nucleus → nuclei
- radius → radii
- focus → foci or focuses
- cactus → cacti or cactuses
- fungus → fungi or funguses
- syllabus → syllabi or syllabuses
- vertebra → vertebrae
- antenna → antennae or antennas
- formula → formulae or formulas
- index → indices or indexes
- appendix → appendices or appendixes

Back to our images:

Image 9: one tooth
Image 10: two teeth → so tooth / teeth

Image 11: one deer
Image 12: two deer → deer stays the same! → deer / deer

Image 13: one foot
Image 14: two feet → foot / feet

Image 15: one wolf
Image 16: three wolves → wolf / wolves

Now what about image 7 and 8?

Image 7: looks like a single fern leaf — but “fern” is regular: fern/ferns. Not irregular.

Wait — maybe it’s “leaf”? Image 7: one leaf? Image 8: two leaves? Yes — that fits. Leaf → leaves is irregular.

So:

Image 7: leaf
Image 8: leaves → leaf / leaves

And image 1 & 2: goose/geese — already done.

Image 3 & 4: knife/knives — done.

Image 5 & 6: man/men — done.

Image 9 & 10: tooth/teeth — done.

Image 11 & 12: deer/deer — done.

Image 13 & 14: foot/feet — done.

Image 15 & 16: wolf/wolves — done.

What about image 7 & 8? We said leaf/leaves.

Is there any other possibility? Maybe “fern” isn’t intended — because it’s not irregular. The worksheet title says “Irregular Plural Nouns”, so all answers should be irregular.

Leaf → leaves is irregular (change f to v + es).

Yes.

Also, note: sometimes “ox” → “oxen” is used, but no ox here.

Another common one: “child” → “children”, but not shown.

So let’s list all 8 pairs (since there are 16 boxes, grouped in pairs):

Pair 1-2: goose → geese
Pair 3-4: knife → knives
Pair 5-6: man → men
Pair 7-8: leaf → leaves
Pair 9-10: tooth → teeth
Pair 11-12: deer → deer
Pair 13-14: foot → feet
Pair 15-16: wolf → wolves

That’s 8 irregular plural noun pairs.

Now, write them as requested: “Write the irregular nouns and their plural form”

So for each pair, we write: singular / plural

Final Answer:

1. goose / geese
2. knife / knives
3. man / men
4. leaf / leaves
5. tooth / teeth
6. deer / deer
7. foot / feet
8. wolf / wolves

Wait — the numbering in the image goes from 1 to 16, but they are paired: 1&2, 3&4, etc. So probably we should list 8 answers, each corresponding to a pair.

The instruction says: “Write the irregular nouns and their plural form” — likely meaning for each picture pair, give the singular and plural.

Since there are 8 pairs (boxes 1-2, 3-4, ..., 15-16), we have 8 answers.

Let me double-check each:

Boxes 1 & 2: goose → geese ✔
Boxes 3 & 4: knife → knives ✔
Boxes 5 & 6: man → men ✔
Boxes 7 & 8: leaf → leaves ✔ (assuming image 7 is one leaf, image 8 is two leaves — even though they look like ferns, in educational context, it's likely "leaf")
Boxes 9 & 10: tooth → teeth ✔
Boxes 11 & 12: deer → deer ✔ (unchanged)
Boxes 13 & 14: foot → feet ✔
Boxes 15 & 16: wolf → wolves ✔

All are standard irregular plurals.

Note: For “deer”, the plural is the same as singular — still considered an irregular plural pattern.

Similarly, “sheep” would be another, but not here.

So final answer should list these 8 pairs.

How to format? Probably as a list.

Since the user didn’t specify format, I’ll write them clearly.

Final Answer:

goose / geese
knife / knives
man / men
leaf / leaves
tooth / teeth
deer / deer
foot / feet
wolf / wolves
