This year we made a super easy Advent calendar paper chain.  The kids decorated the strips of paper and I wrote the activities on the inside. 

Here is a list of some of the activities we will be doing:

Popcorn and Christmas movie night
Make a gingerbread house
Make snowflakes for our front window
Do a good deed for someone
Pick out Christmas books from the library
Bake soft pretzels in the shape of candy canes
Feed the birds
String cranberries and popcorn for our tree (I have always wanted to try this)!
and so on 

The kids love having an activity a day and it helps keep us grounded during this busy season.
