Hi! I am teaching in Japan and I want to get across some pronunciation points in class, specifically the different sounds l and r make. I knew that this would be a struggle, and most of the kids can't even hear the difference between the two sounds. Because the "r" sound is formed within the mouth, it it very difficult to show them how to form the r. I wish I had a good diagram of the inside of the mouth making the "r" sound, but I haven't been able to find any good teaching tools on this point. Any suggestions?
