Show Answer Key & Explanations Step-by-step solution for: Regular and Irregular Plurals worksheet
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.

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