## 🎯 Task 1: Add Singular or Plural Possessive Apostrophes

We need to add:
- Singular possessive apostrophe → `'s` (e.g., *the dog’s toy*)
- Plural possessive apostrophe → `s'` (if plural ends in s) or `'s` (if plural doesn’t end in s)

> 💡 Rule reminder:
> - Singular noun → add ’s
> e.g., *girl’s book*
> - Plural noun ending in s → add just
> e.g., *girls’ books*
> - Plural noun NOT ending in s → add ’s
> e.g., *children’s toys*

Sentence-by-Sentence Solutions:



1. The dogwalker didn't realise she had left behind several dogs toys in the park.
→ “dogs” is plural, and it owns the toys → dogs’
Answer: dogs’

2. Tillys pencil case has gone missing.
→ “Tilly” is singular → Tilly’s
Answer: Tilly’s

3. The boys group project has been ripped.
→ “boys” is plural → boys’
Answer: boys’

4. The pigs pen was barely big enough for him anymore.
→ “pigs” is plural → pigs’
Answer: pigs’

5. We’re going to drive in my sisters car.
→ “sisters” is plural → sisters’
Answer: sisters’

6. The twins birthday cake was raspberry and white chocolate.
→ “twins” is plural → twins’
Answer: twins’

7. Have you seen Jasons shoes anywhere?
→ “Jason” is singular → Jason’s
Answer: Jason’s

8. The monsters head was large and green.
→ “monsters” is plural → monsters’
Answer: monsters’

---

## 🖍️ Coloring Instructions (as per worksheet):

- Red: Singular possessive apostrophes → Sentences 2, 5, 7
→ *Tilly’s, sisters’, Jason’s*

- Blue: Plural possessive apostrophes → Sentences 1, 3, 4, 6, 8
→ *dogs’, boys’, pigs’, twins’, monsters’*

*(Note: Sentence 5 — “sisters’” — is plural possessive, so should be blue. But the worksheet says “my sisters car” — if it meant one sister, it should be “sister’s”. However, since it says “sisters”, we treat it as plural.)*

---

## ✍️ Task 2: Write Your Own Sentences

Use the subjects given and write complete sentences using correct possessive apostrophes.

---

1. The flowers belonging to an old woman.



The old woman’s flowers were blooming beautifully.
*(Singular: “old woman” → ‘s)*

---

2. The basketballs belonging to the team.



The team’s basketballs were lined up on the bench.
*(Singular: “team” → ‘s — even though it refers to many people, “team” is singular)*

> 💡 Note: “Team” is a collective noun — treated as singular unless specified otherwise.

---

3. The nest belonging to the birds.



The birds’ nest was high up in the oak tree.
*(Plural: “birds” → ’)*

---

## 🧾 Final Answers Summary:

Task 1: Corrected Sentences



1. dogs’
2. Tilly’s
3. boys’
4. pigs’
5. sisters’
6. twins’
7. Jason’s
8. monsters’

➡️ Color Red: 2, 7 (Tilly’s, Jason’s) — *Wait! Sentence 5 is “sisters’” — that’s plural, so should be BLUE.*
Actually, let’s double-check:

- Sentence 2: Tilly’s → singular → RED
- Sentence 5: sisters’ → plural → BLUE
- Sentence 7: Jason’s → singular → RED

So red = 2, 7
Blue = 1, 3, 4, 5, 6, 8

*(Sentence 5 is tricky — if it meant “one sister”, it should be “sister’s” — but as written, “sisters” implies more than one → plural → blue.)*

Task 2: Sample Sentences



1. The old woman’s flowers were blooming beautifully.
2. The team’s basketballs were lined up on the bench.
3. The birds’ nest was high up in the oak tree.
