Helping students understand the correct use of “must” and “should” is an essential part of learning English grammar. These two words are called modal verbs. They are used to express duty, advice, rules, and suggestions.
What Are Modal Verbs?
Modal verbs are helping words that express:
- Advice
- Necessity
- Obligation
- Rules

Common modal verbs include words like can, may, might, and will. However, this worksheet focuses only on must and should.
The Difference Between “Must” and “Should”
Understanding the difference between these two is very important.
