Subjects And Verbs
Every sentence has a subject and a verb. The subject is who or what the sentence is about. The verb is the action, like run, jump, or sing. These two must match each other, like good dance partners. When they match, the sentence sounds just right. When they do not match, the sentence sounds a little funny to your ears. So we want them to agree every time.
One Or Many
The big trick is to count the subject. Is it just one, or is it many? When the subject is one, like the dog, the verb adds an s, like runs. When the subject is many, like the dogs, the verb drops the s and stays as run. Watch out! Some words like children and people are already many, even without an s, so the verb still drops its s.
Worked examples
Pick the right verb form
- Find the subject: the rabbit.
- Count it: that is just one, so it is singular.
- A singular subject needs the verb with an s: hops.
Answer: The rabbit hops
Activity
Drag each sentence card into the correct bin — Singular Subject or Plural Subject — based on the subject word in each sentence.
Practice
Choose the verb that matches the subject in each sentence.
Find the sentence that sounds wrong and fix the verb.
Common mistakes to avoid
- No s means singularWords like children and people are plural even without an s ending.

Which sentence uses the correct verb form?
Read the sentence: "The players ___ every morning." Which verb correctly completes the blank?
A student says: "The children runs to the swings." What is wrong with this sentence?
Recap
A subject and a verb must always match, like good dance partners. When the subject is one, the verb adds an s. When the subject is many, the verb drops the s. Say it out loud to check!
