▼
Let’s go through each picture and choose the correct plural form based on the rules shown.

We’ll match each image to its correct plural word, using either regular or irregular plural rules.

---

Row 1:

1. Leaves → “leaf” ends in ‘f’, so Rule 5: f/fe → ves → *leaves* ✔
2. Books → “book” + s → *books* (Rule 1) ✔
3. Dresses → “dress” ends in ‘ss’ → add ‘es’ → *dresses* (Rule 2) ✔
4. Buses → “bus” ends in ‘s’ → add ‘es’ → *buses* (Rule 2) ✔
5. Potatoes → “potato” ends in ‘o’ → usually add ‘es’ → *potatoes* (Rule 2) ✔

*(Note: Some words ending in ‘o’ take just ‘s’, like “photos”, but “potato” is one that takes ‘es’.)*

---

Row 2:

6. Bows → “bow” ends in vowel + y → add ‘s’ → *bows* (Rule 3 exception) ✔
7. Men → “man” → irregular → *men* ✔
8. Cats → “cat” + s → *cats* (Rule 1) — wait! The image shows a cat sleeping with kittens? Actually, it looks like one adult cat and two kittens — but the question is about pluralizing the noun shown. If it’s “cat”, then “cats”. But if it’s showing multiple cats, still “cats”. However, looking again — maybe it’s “kittens”? No, the main subject is likely “cat” → plural = *cats*. But let’s check: actually, the image has one big cat and two small ones — so total 3 cats → *cats*. ✔
*(Wait — correction: The image might be meant to show “cat” as singular, but we’re choosing plural forms for what’s depicted. Since there are multiple animals, it’s “cats”.)*
BUT — hold on! Looking at the image again: It’s an orange cat lying down with two smaller orange cats beside it — so 3 cats → plural = *cats*. ✔
9. Peaches → “peach” ends in ‘ch’ → add ‘es’ → *peaches* (Rule 2) ✔
10. Feet → “foot” → irregular → *feet* ✔

---

Row 3:

11. People → “person” → irregular → *people* ✔
12. Deer → “deer” → same in singular and plural → *deer* ✔
*(Image shows 4 deer — so plural is still “deer”)*
13. Children → “child” → irregular → *children* ✔
14. Watches → “watch” ends in ‘ch’ → add ‘es’ → *watches* (Rule 2) ✔
15. Mice → “mouse” → irregular → *mice* ✔

---

Row 4:

16. Shelves → “shelf” ends in ‘f’ → change to ‘ves’ → *shelves* (Rule 5) ✔
17. Fish → “fish” → can be same in plural → *fish* ✔
*(Image shows 2 fish — so “fish” is correct plural)*
18. Butterflies → “butterfly” → consonant + y → change to ‘ies’ → *butterflies* (Rule 3) ✔
19. Keys → “key” → vowel + y → add ‘s’ → *keys* (Rule 3 exception) ✔
20. Gloves → “glove” ends in ‘e’, not ‘f’ or ‘fe’ → so just add ‘s’ → *gloves* ✔
*(Wait — “glove” doesn’t end in f/fe, so Rule 1 applies: glove + s = gloves. Correct.)*

---

✔ All answers checked against rules.

Final Answer:

leaves, books, dresses, buses, potatoes, bows, men, cats, peaches, feet, people, deer, children, watches, mice, shelves, fish, butterflies, keys, gloves
