One of my classes was on a field trip last week, so I was able to catch up on a bit of housekeeping. It's amazing how quickly an art room can get messy! I also added a few reminder signs, such as:
Last year I had green, yellow, and red footprints on my floor to show the kids where to stand in line. I have step stools for the kids to reach my tall sinks, and it makes me crazy when there's four kids on one slippery step! They're also spaced so that they won't get paint on the back of the kid in front of them when holding a wet pallet.
