Grade 3 worksheet on distinguishing between possessive and plural forms of nouns.

You're working on a Grade 3 Punctuation Worksheet titled “Possessive vs. Plural” from K5 Learning. The goal is to choose between plural (e.g., “boys”) and possessive (e.g., “boy’s”, “boys’”) forms to complete each sentence correctly.

🔑 Key Rule Reminder:

- Plural = more than one of something → add -s or -es
*Example: boys, dogs, houses*
- Possessive = shows ownership → add ’s (singular) or ’ (plural ending in s)
*Example: boy’s (one boy owns it), boys’ (multiple boys own it)*

> 💡 Tip: Ask yourself — “Is this word showing ownership?” If yes → use possessive. If no → use plural.

💡 Teaching Tip:

To help students remember:
> “If it owns something → add an apostrophe!”
> Example: “The dog’s bone” = bone belongs to the dog.
> “The dogs bark” = multiple dogs barking — no ownership → no apostrophe.
