Let's solve this worksheet step by step. The task is to add apostrophes to show possession in each sentence. Remember the rule:

- For singular nouns, add an apostrophe and an s: *Simon’s car*.
- For plural nouns ending in s, just add an apostrophe: *the dogs’ toys*.
- For plural nouns not ending in s, add an apostrophe and an s: *children’s toys*.

Now, let’s go through each sentence:

---

1. Simons car wouldn't start, so Jakes brother bought his car down to help out.



- "Simons" → Simon’s (possessive)
- "Jakes" → Jake’s (possessive)

Corrected:
Simon’s car wouldn’t start, so Jake’s brother bought his car down to help out.

🔍 Key Tips:


- Always check if the noun is singular or plural.
- Use ’s for singulars (e.g., *John’s*).
- Use for plurals ending in *s* (e.g., *dogs’*).
- Be careful with shared possession: *Mandy and Milly’s mother* = one mother.
