A well-made slate board completes the marriage. It is pure joy to come to class with a fully prepared math lesson on yellow legal paper, take attendance, clear the board, and start, filling three, maybe four boards with precise alphanumeric characters, graphs or diagrams, and a confident cadence that allows for good questions, good notes, and a positive learning environment. When good chalk hits good slate there is an immediate sense of responsibility with respect to what has been enabled.
