HO HO HO!
Tomorrow starts the countdown to Christmas. Why not use an online advent calendar with your students. There are quite a few out there to choose from. Here are three that I found that look good.
Advent Calendar #1 -Click Here
Advent Calendar #2 - Click Here
Advent Calendar #3 - Click Here
I have not used these with students before and I have not been able to check them out since I'm writing this post prior to December 1st, which is when the sites become usable. So check them out first before you use them. Let me know if you find other advent calendars online.
Have fun counting down with your students!
