Can you suggest me some fun Christmas-themed game for 6-year-old children in a small classroom?

I plan to celebrate Christmas with my class with some games and give them presents according to their scores in the games. They are 6 years old and just started school so they have problems with understanding complicated commands. My classroom is also a bit small so I can’t really make them run too much. I want some games that are simple to understand and play, fun, not too difficult but also appropriately challenging, and is suitable for a small room. Can you help me come up with some ideas?
