## 25 days of math (with treats)

I love advent calendars. It’s a Christmas tradition that I always wanted and never had growing up, so last year I bought this lovely wooden one on deep discount at a local craft store, after admiring them for years. Of course, I immediately discovered why my parents probably never indulged us in this tradition and why pre-filled calendars are so popular: It can be a serious challenge to find so many tiny things to fit in those drawers–and to be ready by December 1, to boot! But it’s so worth it, especially when I hear all the math noticing happening every day.

With four children, the way I tackle my advent calendar is to divide it up. Last year, I divided the first 24 days by four, so each child got six drawers, and then on Christmas Day they got a shared treat. This year I decided to have more shared drawers, so I divided all 25 days by five, so that every fifth day is a shared treat.

The kids immediately picked up on the new system and proceeded to explain it to their younger siblings. I would like to say that I planned it, but I have to admit is was sheer dumb luck: The calendar is helping my kindergartner learn to count by fives!

“Look, Mom, my days all end with two or seven! Malcolm, your days end with one or six, see? And on the five and zero days we all get a treat!”

Another bonus to the calendar is that I have a pat answer every morning to the inevitable question, “Mom, how many days until Christmas?”

“Go check the advent calendar and count.”
