Class 6 Grammar Worksheet on Verb Forms – Principal and Auxiliary Verbs

Do the Action or Help It: Principal and Auxiliary Verbs for Class 6

This Grade 6 worksheet teaches learners to distinguish between principal (main) verbs and auxiliary (helping) verbs like *is, am, are, was, were, have, has, had, do, does, did*. With sentence analysis, form-based exercises, and verb correction tasks, students understand how both verb types work together in real-world grammar.

Why Principal and Auxiliary Verbs Matter in Grammar?

Understanding these verbs builds a foundation for tense, agreement, and structure. For Grade 6 students, this is important because:

1. Principal verbs show what the subject is doing.

2. Auxiliary verbs help express tense, mood, or voice.

3. Knowing both improves grammar accuracy in all tenses.

4. It sets the base for advanced grammar like voice and aspect.

This worksheet includes five scaffolded grammar activities to explore verb forms:

🧠 Exercise 1 – Underline and Circle

📋 Exercise 3 – Fill in the Blanks

📝 Exercise 4 – Rewrite the Sentences
