What and on what did the ancient Greek schoolchildren write?

Elementary schoolchildren learned to write on tablets that had been waxed. The letters on them were squeezed out with the sharp end of a stick, which was called a style. Older students wrote on papyrus using a reed pen and ink. It is worth noting that the Greeks borrowed papyrus from the ancient Egyptians, or rather bought it from them. At that time, trade was well developed, given the Greeks’ desire for trade. Naturally, the most advanced writing material was the Egyptian papyrus.
