This year, our school has started with P.E. lessons in English, in primary school.
Once a week half of the students in the classroom have P.E. lesson in English, while the rest of the students are at English lesson. After forty five minutes they change. We do the same from the first to the sixth level.
I think that it´s a very good way of learning English.
Here you have an example of a volleyball lesson with students from the fifth level.
