Here’s an activity you can use for first, second or third conditional. I’ll use third conditional for this example;
Dominoes; put the tables in two rows, and split the class in half. Hand out pieces of paper with half sentences written on them to each team. Make sure you have; the beginning of the sentence and the end part of the sentence.
In this game, the class has to make up the conditional sentence. They place the slips down on the table and each team takes a turn to make up sentences:
“If I had studied harder, I would have passed the exam.” “If I had accepted the money, I would have been rich.”
