In pairs, students compete against other teams to create a long Chain of Events.
  The conversation might go something like this:
   Student A: I'm so glad I did my homework last night.
   Student B: What would have happened if you hadn't done your homework last night?
   Student A: If I hadn't done my homework last night, I would have had to do it this morning.
   Student B: What would have happened if you had had to do it this morning?
   Student A: If I had had to do it this morning, I wouldn't have had time for breakfast.
   Student B: What would have happened if you hadn't had time for breakfast?
   Student A: If I hadn't had time for breakfast, I would have had to eat on the bus.
   Student B: What would have happened if you had had to eat on the bus?
   Student A: If I had had to eat on the bus, the bus driver would have become angry.

    The real beauty of this lesson is the way it creates energy among the students. As they literally build their Chains, they automatically watch the progress of the other groups which only encourages them to add more and more links.
    They'll be so busy adding to the Chains that they won't realize they are working with a fairly difficult grammar tense - Past Perfect Tense with Type 3 Conditionals!!

    And, perhaps more importantly, they WILL be able to do it!

    There is another worksheet in this series. See:
