- Ought to: Suggests a moral obligation or duty (e.g., “You ought to respect your elders.”)
- Provide Examples and Non-Examples:
- Example (Must): “We must arrive at school before 9 o’clock.”
- Non-example: “We can arrive at school after 9 o’clock.” (Incorrect use of ‘must’)

- Non-example: “I ought to take the bus to school.” (Incorrect use of ‘ought to’)
- Example (Ought to): “You ought to help your friend in need.”
- Non-example: “You must help your friend in need.” (Incorrect context for ‘must’)
- Illustrate with Visual Aids: Use charts to show the different contexts for ‘must’, ‘have to’, and ‘ought to’.
