A child in my class forgot their pencil. I was informed of this only because of the nature of the solution to the problem: Fashion a makeshift fountain pen out of a disposable chopstick, tissue paper, and marker ink.
A written math assessment was perfectly legibly completed with this implement.
I'm sure many teachers would have simply demanded that it be cleaned up and provide the child with a pencil. It's clearly a giant mess hanging from a wobbly precipice and not a remarkably responsible way to accept one's mistake.
However, my respect for creativity, ingenuity, and other Maker values endowed me with the patience to request clean up after the quiz was finished. I think that the leeway the student was allowed not only helped them to feel empowered, but also encouraged voluntary cooperation with more orthodox classroom procedures.
