• Subject-verb agreement is a fundamental aspect of the English language that students learn starting in the fourth grade. In a sentence, the subject refers to the noun or pronoun that performs the action, while the verb indicates the action taken by the subject. For instance, in the sentence “The dog barks,” “dog” is the subject, and “barks” is the verb. Correct subject-verb agreement involves ensuring that the verb agrees with the number and person of the subject.

    Below are some rules that fourth-grade students need to follow to ensure proper subject-verb agreement:

    1. Singular subjects require singular verbs, while plural subjects require plural verbs. For example:

    – The boy runs. (singular subject and verb)

    – The girls run. (plural subject and verb)

    2. If there is a compound subject involving two or more nouns, use a plural verb. For example:

    – The cat and the dog play together. (plural verb)

    3. When the subject is a collective noun representing a group of individuals, the verb can be either singular or plural, depending on the context. For example:

    – The audience applauds the performance. (singular verb, treating audience as a group)

    – The audience disagree on the topic. (plural verb, treating audience as individuals)

    4. When the subject is a proper noun, such as a name of a person or place, always use a singular verb. For example:

    – John loves playing basketball. (singular verb)

    5. When the subject is indefinite, such as “someone,” “anyone,” “everyone,” or “nobody,” use a singular verb. For example:

    – Someone is knocking at the door. (singular verb)

    By following these simple rules, fourth-grade students can ensure that their sentences have proper subject-verb agreement, making them clear and grammatically correct.
