It´s a kind of game because when I need to practice grammar I could use this activity. I give students sentences in their mother tongue and they have to traslate it in English or German.When they do mistake they can´t sit down. If they say it right, they can sit down. The last person has to do some task that will be given to him by the other students. It could be really funny activity esp. at the end when the learner has to do the task.
