Before the lesson
Introduce a familiar classroom rule and a piece of advice. The sheet is an explanation resource, not a gap-fill task, and has no answer key.
- Compare You should rest, You must stop and I have to work, discussing the speaker's meaning rather than assigning every obligation one rigid category.
- Practise should / must + base verb and have / has to + base verb. Contrast You mustn't smoke here with You don't have to come early.
- Read the additional examples, then ask learners to explain one rule, one optional action and one piece of advice in their own words.
Support and extension
Support with prohibited / required / optional / advisable labels. Extend by changing a positive rule into both negative forms and explaining their different meanings; must and have to can overlap in real contexts.
Suggested approach. Adjust the pace and number of questions to suit your class.
