I’ve always thought that talking about numbers gets short shrift (not enough attention) in most language classes. People talk about numbers a lot in normal conversation, and we hardly ever practice them in class. I’d like to do a whole class about using numbers in English. I think it would be a blast.
I’d certainly use this site in that class, What Japan Thinks is a look at Japan through questionnaires and statistics. I think it is a great way to talk about Japan, and about people.
