Possessive Nouns — Answer Key
Part A: Sort the Words
Sort each word or number into the correct category box.
1. Sort each phrase into With 's (singular possessive) or With s' (plural possessive).
With 's
Tom's bookthe boy's capAnna's pencil With s'
the teachers' loungethe friends' secretthe cats' toys Plural nouns ending in s take only an apostrophe after the s, while singular nouns add 's.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The dogs' toys are in the box. (dogs)
Plural nouns ending in s form possessives by adding just an apostrophe.
2. The teachers' lounge is on the second floor. (teachers)
Plural teachers already ends in s, so we add only the apostrophe.
3. My friends' house is near the park. (friends)
When many friends share something, use friends' with the apostrophe after the s.
4. The kids' bags are on the bus. (kids)
Kids is plural and ends in s, so we add only an apostrophe to show ownership.
5. The cats' tails are fluffy. (cats)
Cats is a plural noun ending in s, so the possessive is cats' with the apostrophe after s.
Part C: True or False?
Read each statement. Circle True or False.
