After I had published the blog about immigrants to New York; I found this resource. It develops an understanding of the issues of migration and associated vocabulary. It is broad in it's perspective and sensitively written.
There is a vocabulary definition exercise, a video, a matching exercise matching individuals to different reasons for moving, true/false questions, an opportunity to order words in sentences and a gap fill exercise using adjectives.
It is probably a
simpler resource so it could be tackled first to build
up an understanding of the main issues. Some students may want to
just tackle this resource on it's own. Go to Communicative Resources Page
