Interactive worksheet for teaching possessive nouns with engaging exercises and visual aids.

Problem Overview:

The task involves completing sentences using possessive nouns and writing sentences that include possessive nouns. Possessive nouns are used to show ownership or possession, typically formed by adding an apostrophe and "s" (e.g., "John's book") or just an apostrophe for plural nouns ending in "s" (e.g., "the dogs' toys").

Solution:

#### Part 1: Complete the sentences using possessive nouns from the box
The given possessive nouns are:
- my
- his
- her
- our
- their

Let’s complete each sentence:

1. My dog is very cute.
- The subject is "I," so the possessive form is "my."

2. Her cat is sleeping on the couch.
- The subject is a female, so the possessive form is "her."

3. Their house is very big.
- The subject refers to multiple people, so the possessive form is "their."

4. His car is parked outside.
- The subject is a male, so the possessive form is "his."

5. Our team won the game.
- The subject refers to a group including the speaker, so the possessive form is "our."

#### Part 2: Write sentences using possessive nouns
We need to write sentences that include possessive nouns.

1. The teacher's desk is covered with papers.
- Here, "teacher's" shows possession of the desk by the teacher.

2. The children's playground is full of laughter.
- Since "children" is already plural, we add only an apostrophe to show possession.

3. The cat's tail is fluffy.
- "Cat's" shows possession of the tail by the cat.

4. The students' books are on the table.
- Since "students" is plural, we add only an apostrophe to show possession.

5. The farmer's barn is old but sturdy.
- "Farmer's" shows possession of the barn by the farmer.
