hi everyone,I've been teaching some girls aged 13 to 16.my problem is how to deal with them in teaching,i explain the lessons very completely, i give them some pair work, we play some games, but it seems they're not interested at all.most of the time they look at their watches and want to get out of the class.i really don't know what to do to have their attention and interest to the lessons?can anyone help me?thanks a million.
