Hi! I am a school teacher in Belarus. I think you've got a great idea.
I'd like to arrange a Skype-lesson for your students and mine which are 11-13 years old. I'd like to let them talk on-line about summer holidays (for this is the currant topic according to the school program) of Polish and Belarusian schoolchildren, using vocabulary and grammar learned in September. I have computer in the classroom and will try to connect a webcam too.
If you are willing, please contact me for discussing more detailed so that we could lead their talk according to our teaching aims.
