Help with Phonemes!

[keano]

I need help coming with an communicative activity for a class. I have to teach the phonemes l and r. I have come to the end of my class and need to come up with a communicative task for the students at the end. I have been searching for a suitable game/activity but cant seem to find the right one. Any suggestions would be great. Thanks

Which country are you teaching in? Are you teaching students who have serious problems distinguishing between these two sounds? What level are the students? How many are there in the class?
