Art on a Cart.... for a week! Yikes!

It's that lovely time of year where students are taking standardized testing!  So that means that the art room is officially closed.  It is used for testing all this week, so that means that I'm on a cart all week.  It can be hard to change from your own space to using another teacher's space for art.  To paint or not to paint, that is the question! I have to choose my art lessons wisely this week! Any suggestions out there?  It definetely makes me feel grateful for having my own classroom, my own space.  I must take my hat off to all the art teachers out there that are on a cart 24/7!  It's not easy!
