What is a "slate"?
A slate is a flat piece of stone traditionally used as a writing surface, especially in schools before paper became widely available. It is often framed with wood and written on using a slate pencil or chalk. Slates were reusable, as the writing could be wiped off, making them practical for practicing writing or arithmetic. Today, the term can also refer to similar writing surfaces used for artistic or decorative purposes. Slates were an important tool in education, offering an inexpensive way to learn and communicate.
