This is the third in a series of very short videos showing a child using loose parts to make his own construction. As the video starts, he balances a little metal pail on top of his construction of a cardboard tube in a coffee can with a plastic measuring cup on top. It is worthwhile to note that he is not hovering close to the construction like he was earlier when he was not so sure it would stand by itself. At this point he begins to experiment with what he can add to the structure and have it remain stable. He is standing and using his whole body to showing his excitement with his endeavors. It is almost like a happy dance with his body and arms swaying to and fro. He quickly removes the metal pail and returns it to the shelf He finds another plastic measuring cup and very carefully places it over the plastic measuring cup already sitting atop the cardboard tube. He takes a quick step back to admire his work. His "huh, huh" exclamation a proud proclamation of his work. Again, his whole body oozes with excitement at endeavor. He carefully removes the plastic cup he has just placed on the structure. As he does that, he looks at the numbers on the side of the measuring cup. He understands the concept up numbers because he says: "I just count to 100." The video ends with the child bending down and looking at his structure and broadcasts another "huh, huh."
