Countdown to winter break begins

This is the last week of school for calendar year 2007. This week is going to be expecially challenging for me since I have all seniors. Keeping them focused and working is going to be a chore and I imagine that by the end of the week I'll have very few students. Some will be leaving early for break while I'm sure others will be hanging out with other teachers and their class parties. I'm thinking I might need to end this week with a quiz.....
