UPDATE: Full list of my own Xmas stuff now here.
So, I might have left this list of Xmas links for TEFL purposes a bit late, but here goes anyway:
ee cummings poem about Xmas with gaps and recording
A list of movies with a Xmas theme suitable for class or to recommend to students
A huge list of Xmas discussion questions (not to be given to students just like that unless you are planning a dossy lesson as an early Xmas present to yourself!)
And almost as huge a list, but this time discussion questions just about Santa from Breaking News English (a good site if not overused!), plus a few more Xmas ideas
A list of Xmas superstitions (a first conditionals worksheet on this coming up from me on Usingenglish.com soon)
And talking of Xmas stuff on Usingenglish.com, I can honestly say that all that stuff above from maybe 100 pages I looked at have not made me at all shy of my Xmas worksheets and they remain highly recommended, though I say so myself…(see also, Xmas themed posts below).
