Subject-Verb Agreement — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The mailman delivers letters to our house every afternoon.
"The mailman" is one person, so it is singular. Singular subjects take a verb ending in -s, making "delivers" the correct form.
2. The puppies wag their tails when they see their owner.
"The puppies" is plural because it refers to more than one puppy. Plural subjects use the base form of the verb, so "wag" is correct without the -s.
3. My aunt makes pancakes for breakfast every Sunday.
"My aunt" is one person, so it is a singular subject. Singular subjects need the -s form of the verb, so "makes" is correct instead of "make."
4. The windows are open because it is warm outside.
"The windows" is plural because there are multiple windows. Plural subjects pair with "are," not "is," so "the windows are" is correct.
5. That store sells fresh bread every morning before sunrise.
"That store" is singular because it refers to one store. Singular subjects take a verb with -s, so "sells" is the right choice.
6. The crickets are so loud at night near the pond.
"The crickets" is plural because it means many crickets. Plural subjects use "are" as their linking verb, so "the crickets are" is correct.
7. Our principal reads the morning announcements at nine.
"Our principal" is one person, so the subject is singular. You add -s to the verb for singular subjects, giving you "reads" instead of "read."
8. The monkeys at the zoo swing from branch to branch.
"The monkeys" is plural, so the verb uses the base form without -s. "Swing" matches the plural subject, while "swings" would only fit a singular subject like "the monkey."
9. That little kitten has a white spot on its nose.
"That little kitten" is one kitten, so it is singular. Singular subjects use "has" instead of "have," so "the kitten has" is correct.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
The doctor
→ helps sick people.
fall from the tree.
The rabbits
→ hop across the field.
helps sick people.
My dad
→ cooks dinner for us.
hop across the field.
The leaves
→ fall from the tree.
cooks dinner for us.
Singular subjects like "the doctor" and "my dad" take verbs with -s (helps, cooks). Plural subjects like "the rabbits" and "the leaves" take verbs without -s (hop, fall).
