Have just put up a new one that reviews future tenses and ties some of the older ones together:
Xmas and New Year Xmas tense review
I used it with these activities to make a 90 minute lesson:
Going to for plans and predictions Xmas mimes
Will for future predictions Xmas
Xmas first conditional superstitions bluff game
and was planning to move onto this if I had time:
Future Perfect New Year predictions
or just improvise some practice where they made arrangements over the Xmas period (Present Continuous) or told each other their plans and offered to help each other (will for spontaneous decisions).
There are also these two on future tenses and the festive season:
New Year Future Continuous action and state verbs
New Year resolutions adverbs of frequency – going to for plans and learner training
If that’s not enough, far more Xmas and New Year worksheets than can possibly be healthy here:
