[Grammar] telf help

[ck87]

Hey everybody. I'm currently stuck on this question. I need to think of a communicative task for teaching the phonemes /l/ and /r/. I need to have the students using the target language in a freer, more natural way - for example in a role play. If anybody can give me advice it would be much appreciated. Thanks

How basic is their English? Have they never come across these sounds- if so, they're unlikely to be communicating freely.
