What will the Keshet children do with the tube?

As Savita unrolled the new rug in our classroom, we found a thick cardboard tube inside.  We propped one end of it on a chair and waited to see what the children would do with it.  They looked it over, looked through it, looked through it at each other, talked and yelled to each other from one end to the other.  Eventually, the children started placing things inside the tube: cars, trucks, train cars, and then....Lego pieces.  They came to understand that the Lego pieces would not slide to the end of the tube like the wheeled vehicles did.  At one point, the tube was filled from one end to the other with objects.  This play also offered another opportunity to work on taking turns.
