Exchanging letters with US-students

I‘m a German teacher, teaching English in grade 8 (14 year-olds) in a bigger city. This year our topic is the US :us: I have 24 students.
A former class and me enjoyed a letter-exchange for a whole school year with around four letters going back and forth. I‘d like doing this again :smiley:
Are you an American teacher (preferably at a high school with freshmen) interested in writing in English?
