That question was followed up by another, related question: How do I deal with conflicts at the table? I said---a little too flippantly---that there are no conflicts at the sensory table. Of course, that is not true, so what do I really do?
The first thing I do is set up the environment. That means building the apparatus. What that does is create complex and intriguing spaces that invite many types of play and exploration. That allows the children to be agents in their most important endeavor: transporting. (See axiom #1 in the right-hand column.) And since they can do it constructively in a variety of ways, they negotiate and accomodate with others with little or no prompts. Take a look at the video below showing children interacting in a complex and intriguing space and pay special attention to the three boys at the beginning of the video who, without conflict, are essentially operating in the same space.

If I have not convinced you to this point, maybe a comment from a teacher who attended the presentation I did at the Wisconsin early childhood conference in the fall of 2011 may sway you.
