I ment it like a sort of final lessons for every topic at school so that our students could meet schoolchildren from another country and discuss their interests in comparison with those abroad using English skills in a real comminicative situation in the lesson.
Sure we should exchange vocabulary and grammar material with the teacher in advance to lead the students' talk in the best teaching way.

If you are a EFL teacher with students aged 11-14, please contact me here or per email: theaprilmoon@yandex.ru or per Skype: theaprilmoon.
Best wishes,
