Modal Verbs Worksheet for Adults — Can, Could, Should, Must, May

Modal Verbs Worksheet for Adults — Can, Could, Should, Must, May

Modal verbs (can, could, should, must, may, might, will, would) are how adults express possibility, permission, obligation, and advice. But they’re tricky: they have multiple meanings depending on context, and they don’t follow regular verb patterns.

This worksheet teaches the modal verbs adult learners need most, with clear rules, contextual practice, and real-life scenarios.

What This Worksheet Covers

• Ability: can, could, be able to
• Permission: can, could, may, might
• Obligation: must, have to, should, ought to
• Advice: should, ought to, had better
• Possibility: may, might, could
• Certainty: must, have to, will, would

40+ exercises covering meaning, form, and contextual use.

How to Use This Worksheet

Section 1-3 (25 min): Students complete exercises on meaning and form.

Section 4-5 (15 min): Contextual practice — students choose the right modal for each scenario.

Why Adults Need This Worksheet

Adults use modal verbs constantly: “Can you help me?” “You should try this.” “May I sit here?” “I could help tomorrow.” Understanding modals is essential for both comprehension and production. This worksheet teaches both.
