Subject-verb agreement is an essential part of sentence construction, and it is crucial to get it right for effective communication. In simple terms, subject-verb agreement refers to the correct matching of the subject of a sentence with the verb that is used with it. For example, if the subject of a sentence is singular, then the verb that follows it should also be singular. Similarly, if the subject of a sentence is plural, then the verb that follows it should also be plural.

Class 7 is an important year for students to learn and understand subject-verb agreement rules for clear communication. To help them master this concept, here are some exercises they can practice:

1. Complete the following sentences by choosing the correct verb form:

a. The dog and the cat __________ playing in the garden. (is/are)
