We just had a Christmas party at my school. It was organized by my boyfriend and I, like the Halloween party. Between 60 and 80 kids showed up, but it went pretty well. We separated them among our three English classes, we made Christmas tree decorations, played bingo and hot potato with wrapped gifts, and finished off with some movies and snacks. The kids were all happy, my coworker dressed up as Santa to surprise them and they all got a small gift, and everyone had fun. Here is the before and after picture of the Christmas tree we made (one in each classroom):

ETA: Today is the Winter Solstice Festival, so there are lots of fire works and the lady from upstairs brought us a huge plate of dumplings. So yummy!
