This boardgame is aimed for students studying conditional sentences. It's easily adaptable and can be used to practice any of the conditionals. The idea is that the students play in pairs or groups and they have to form a conditional sentence. E.g. "You can have any animal as a pet" -> "If I could have any animal as a pet, I would have a chimpanzee". The teacher can also tell them to form the sentences in the past (If I could have had any animal as a pet when I was a kid...).
Obviously the board can be used to practice other things as well, such as verb tenses or vocabulary (e.g. "You can travel to any country" -> pairs list countries and choose the one they'd travel to) or the sentences can even be used as as conversation topics.
