"The child in the photo above just received the most amazing toy! It might have been a giant stuffed giraffe, or a truck, or a new game. However, the cardboard box is even more exciting. The child will eventually outgrow the giraffe or the truck because those toys can be only one thing -- but the box is timeless. The box can be a racecar, a submarine, a suit of armor, a castle, or a cave.
We can learn a lot from children's infatuation with cardboard boxes. It shows us how much they want to shape and construct new things, how they long for the freedom to create. In fact, as illustrated by the phenomenon of Caine's Arcade, when students gain the freedom to explore, to learn independently, and to share their creations, they will astound us. Consider the fact that one boy's cardboard arcade inspired thousands from around the world to create and share their own inventions."
