I am so glad that, in addition to my white board space, I have a rolling white board with two sides of writing space. The artist stands at the side of the board and disappears behind it whenever some new detail is added to the CI.
That artist, by the way, must observe the same rule #7 (benslavic.com/resources/posters/classroom rules) that the actors must observe – she must synchronize what she draws with my words, adding nothing else. She uses colored markers.
Another benefit of the rolling board is that we can audition people for jobs behind it, and we can also move it so that there is much less distance between me and the kids during the CI. I have always thought that white boards attached to the walls are too far away from the class.
