One of my favorite things to do with the kids is Saint Nicholas.
Every year, the kids listen to the story of Saint Nicholas (I tell it to them in English, as there is a lot of vocabulary they wouldn't understand...I also take the photos and put them on a PowerPoint without the words. I crop out the knife in the photo with the butcher to tone down the violence). After listening to the story, we discuss it and make some comparisons to Saint Nicholas and Santa Claus. It's amazing how students finally make that connection.
Once we are done discussing, the students get to choose a shoe (I just google the word "shoe" and print off a few colorable ones), color it, cut it out, and tape it to the wall. Then, if they are good little boys and girls, Saint Nicholas comes the night of the 5th of December and tapes a candy cane to their shoe. He did not disappoint this year!
It definitely makes for some good decorations.
