A simple way to teach it
Before the lesson
Refer to the left-late / left-earlier picture; keep actual events separate from the imagined alternative.
- Reconstruct the bus example: they left late and did not catch the bus. Then read the imagined earlier departure.
- Mark had left and would have caught as two past forms. Compare affirmative and negative examples, including had not missed.
- Choose a message or booking example and ask pairs to state the actual situation before reading the alternative. Check participles rather than treating the guide as a gap-fill sheet.
Support and extension
Support with an actual/imagined timeline. Extend with fictional past decisions, so learners need not discuss personal regrets; compare the two clause orders.
Suggested approach. Adjust the pace and number of questions to suit your class.
