Plural and Possessive Nouns — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The book that belongs to the boy is the boy's book.
Boy's shows the book belongs to one boy, using apostrophe s.
2. The hat that belongs to Maria is Maria's hat.
Maria's means belonging to Maria, a Grade 3 possessive form.
3. The bone that belongs to the dog is the dog's bone.
Dog's shows ownership of the bone by one dog in Grade 3 writing.
4. The toys that belong to the children are the children's toys.
Children is an irregular plural, so we add apostrophe s for possession.
5. The nest that belongs to the bird is the bird's nest.
Bird's shows the nest belongs to one bird, a Grade 3 possessive.
6. The car that belongs to my parents is my parents' car.
Parents' uses just an apostrophe because parents is a plural ending in s.
7. The desk that belongs to the teacher is the teacher's desk.
Teacher's shows the desk belongs to one teacher in Grade 3 writing.
8. The wool that belongs to the sheep is the sheep's wool.
