Hi there,
Since nobody volunteered, I �ll give it a try ;-) Personally I liked 2 coursebooks: New Inside Out by Macmillan and English File by Oxford University Press. Have to warn you here - none of these is purely focused on communication but I believe that if you are only starting your adventure with English, you simply HAVE to learn some grammar, be able to listen and read. It �s too early to specialize.
Now the advantages of each:
New Inside Out has a brilliant thing called Anecdotes in every unit (if I remember correctly). First the students listen /or read on a certan topic, then they have to describe a story from their own experience (they have questions to help them). Works great! On top of this there are various games and photocopiables in the TB as well as a dvd.
English File - is more balanced as far as a coursebook is concerned but in the TB there are 3 types of extra photocopiable exercises: grammar, vocabulary and COMMUNICATIVE. After all, it �s your choice what you include in your class :-) There is a film, too - on a dvd rom included in the SB.
Below is the link to both these books - have a look:
