When it rains, my roof leaks. When my roof leaks, the walls get wet. When the walls get wet, they get moldy. When they get moldy, I get sick. When I get sick, I go to the doctor. When I go the doctor, he always says the same thing, "Fix your roof!" Then, I repeat the story substituting 'whenever', 'every time' and 'if'. They guess the rule and I present / write it on the board. Then I present examples of other uses, scientific truths etc. This is followed with multiple choice sentence practice, a cloze activity and their writing their own little story. After that, I point it out to them whenever it comes up in readings, and recycle it for comparative purposes when doing 1,2, and 3, just as a reminder. After studying all 4 conditionals, I give them a type recognition activity - a long reading filled with 30 conditionals."..
