Teaching Modal Verbs
A modal verb is a special kind of helping (auxiliary) verb that adds meaning to the main verb. Modals are never used as main verbs or finite verbs. There are nine modal verbs in English: will, would, can, could, shall, should, may, might, and must. Modals use the same sentence structure as other auxiliary verbs to form sentences and questions.
Sentence & Question Structure
- Sentence: Subject + Modal + Verb
- Example: He can swim.
-
Question: Modal + Subject + Verb
-
Example: Can you swim?
Modal Verbs Express Different Concepts
Modal verbs can convey a wide array of concepts. Some modals convey several different concepts depending upon the context.
- Asking Permission Can I go outside?
- Expressing Possibility I might buy a new bike.
- Give Advice / Suggestion You should go to the game.
- Expressing Certainty They will come tomorrow.
- Expressing Probability It may be sunny.
- Expressing Willingness / Refusal I could help you.
- Making Requests /Offers Would you help me?
- Expressing Obligation/Necessity You must be on time.
- Expressing Ability I can drive a car.
Teaching Modals
Because modal verbs are used in common everyday conversation and written communication, they are taught at all levels of English.
1. Beginning Level: Modals are used for communication purposes. Students learn to express ability, state possibility, make requests, and ask permission.
- Ability: I can play the guitar.
- Possibility: It might rain tomorrow.
- Requests: Can you help me?
- Permission: May I go to the park? Yes, you may.
2. Intermediate Level: Students learn new modals that can be used to give advice/suggestions and express obligation/necessity.
- Advice: You could email or text them.
- Obligation: You should be on time for your appointment.
Also the subtleties of modal meanings are taught at the intermediate level.
- Formal: Would you please ___?
- Polite: Could you please ___?
- Informal: Can you ___?
- 100%: It will rain tomorrow.
- 50%: It may rain tomorrow.
- 10%: It might rain tomorrow.
3. Advanced Level: Students learn how to use past forms and conditional phrases using modals.
- When I was young I could run fast.
- I would have gone to school but I was ill.
General Rules for Modals
Because a modal verb can have several meanings, their meaning is always determined by the context. So when teaching modal verbs students should be warned about the following:
1. Do Not Translate Directly. Define the meaning of the modal by the context of the conversation or passage.
2. Modals Can Have Multiple Meanings. Do not assign a modal verb one meaning. The modal 'can' is used to express a variety of meanings.
- Ability I can play the piano.
- Request Can I go to the watch T.V.?
- Permission Yes, you can go to the show.
- Possibility We can win beat this game.
- He can speak four languages.
- NOT - He can to speak four languages.
- He can swim.
- NOT - He cans swim.
- She could have read the book before.
- NOT - She could has read it before.
5. Negative Statements. Add 'NOT' After the Modal Verb and before the main verb. Use 'could not, may not, might not, should not, will not, must not, will not, and would not'. Exceptions include cannot and semi-modals. Do not add the words 'don't, doesn't, won't, isn't, aren't, wasn't, or weren't'.
- You should not use a pen.
- NOT - You don't should use a pen.
6. Semi-Modal Verbs include ought to, have to, be able to, need to, going to, supposed to, and had better. These have a different grammar and that must be learned.
We hope these suggestions are helpful for teaching English Learners of all levels about Modal and Semi-modal Verbs.
Happy Teaching!
