Sure! Let’s solve the worksheet “Making Regular Nouns Plural” step by step.

---

## Part A: Read the list of singular nouns. Rewrite each one and add “s” or “es” to make it plural.

We need to apply the basic rules for forming plurals in English:

- Most nouns → just add “s”
- Nouns ending in s, x, z, ch, sh → add “es”
- Nouns ending in consonant + y → change “y” to “i” and add “es”
- Nouns ending in vowel + y → just add “s”
- Some irregular nouns (like “child → children”) — but this sheet focuses on *regular* plurals.

Let’s go row by row:

Column 1: SINGULAR → PLURAL

1. apple → apples ✔ (add “s”)
2. blanket → blankets ✔
3. box → boxes ✔ (ends in “x” → add “es”)
4. cat → cats ✔
5. computer → computers ✔
6. day → days ✔ (ends in vowel + y → add “s”)
7. desk → desks ✔
8. dress → dresses ✔ (ends in “ss” → add “es”)
9. egg → eggs ✔
10. frog → frogs ✔
11. key → keys ✔ (vowel + y → add “s”)
12. lady → ladies ✔ (consonant + y → change y to i, add “es”)

Column 2: SINGULAR → PLURAL

1. kite → kites ✔
2. lunch → lunches ✔ (ends in “ch” → add “es”)
3. monkey → monkeys ✔ (vowel + y → add “s”)
4. mouth → mouths ✔
5. note → notes ✔
6. party → parties ✔ (consonant + y → “y” to “i” + “es”)
7. pot → pots ✔
8. snake → snakes ✔
9. teacher → teachers ✔
10. watch → watches ✔ (ends in “ch” → add “es”)

✔ All done!

## Part B: Read the following sentences. Rewrite each sentence to make each underlined noun plural. Edit any other part of the sentence to make it correct.

We must:
- Change the underlined singular noun to its plural form
- Adjust verbs or pronouns if needed to agree with the plural subject

Let’s do each one:

---

1. The bird flew from the tree to the birdhouse.

→ “bird” is singular. Plural = birds

Also, verb “flew” is past tense and doesn’t change for plural subjects — so we keep it.

✔ Corrected sentence:
> The birds flew from the tree to the birdhouse.

*(Note: “birdhouse” stays singular unless specified otherwise — it’s not underlined, so we don’t change it.)*

---

2. Please put this book in your backpack.

→ “book” → plural = books

Also, “this” refers to singular — must change to “these”

✔ Corrected sentence:
> Please put these books in your backpack.

---

3. My brother is going to summer camp.

→ “brother” → plural = brothers

Verb “is” must change to “are” to agree with plural subject.

✔ Corrected sentence:
> My brothers are going to summer camp.

---

4. Look at the cute little boy!

→ “boy” → plural = boys

Also, “the” stays, but since we’re talking about multiple boys, we might want to adjust phrasing slightly — but grammatically, we can say:

✔ Corrected sentence:
> Look at the cute little boys!

*(Note: “cute little” still works with plural — no change needed there.)*

---

5. What country did you visit?

→ “country” → plural = countries

This sentence is already in past tense (“did you visit”) — that structure works fine with plural too.

✔ Corrected sentence:
> What countries did you visit?

---

💡 Summary Tip: Always check if changing a noun to plural affects the verb (e.g., “is” → “are”) or determiners (e.g., “this” → “these”). That’s the key to making sentences grammatically correct!
