A simple way to teach it
Before the lesson
Print the single page or display it as a reference. This is an explanation sheet, not a gap-fill exercise, so there is no answer key. It works best when learners have already met have / has + past participle.
- Compare the timelines: for answers how much time, while since identifies when the period started. Point out that both examples continue to now.
- Sort the supplied expressions into lengths of time and starting points. Include since I was a child to show that the starting point can be a clause, not just a date.
- Read the six examples and discuss I have not eaten anything since breakfast. Then invite learners to make one true sentence about studying, working or knowing someone, using the sheet for support.
Support and extension
For support, contrast for three years and since January before introducing clauses. For an extension, ask learners to express the same ongoing situation with both for and since when they know the start date and duration. Avoid treating since 2018 as a duration: it names the starting point.
Suggested approach. Adjust the pace and number of questions to suit your class.
