Paper. A school is dependent on paper. This thin, white, innocuous object has value beyond what is initially seen. Paper marks the flow of ideas and learning throughout the school. It is hard to imagine a school without paper. Yet, each year imagining a school without paper becomes easier to imagine.
Paper is an indicator species for resources in the school. Paper represents the health and strength of the school. Paper is symbolic of other resources within the school such as writing utensils, novels, additional support in the library, or clubs to create school culture.
Paper, and that for which it represents, is another item I will include on my list of Invisibles.
