I wonder if you know an easier way to help the students know the difference between compound nouns and just simply a noun phrase. You know, I started teaching it today but I found it a bit difficult for them to make compound nouns as I asked them to provide some examples. They gave me examples like 'cold day, formal clothes'. I wrote two sentences with 'green house' as a compound noun and as a noun phrase and I also I told them about white house, with a difference in stress. However, it wasn't very good enough. I'm looking for a better way, some tips or whatever to help them more.

Thanks a million.
