Christmas decorations

I am off to decorate our "school room" with my kiddos. Since I home-school, we have a room in our house that is a den and school room. We usually do all of our Christmas decorating on Thanksgiving weekend. However, this year I only managed to get about half of it done. Since I am back in school, that was the only week that I had off. I greatly enjoyed the down time and spent a lot of my time just relaxing with my family. Now, I'm off to help the kids decorate their tree, and put up lights in our school room. I love moments like these with my kids - they have so much fun! What do you do with your kids to celebrate Christmas? I'd LOVE to hear about it!
