The author has recently been experimenting with having students work at a set of six blackboards mounted on the walls of a maths teaching space. In this article, he describes this project which he started because he had become impatient with, and aggravated by the usual setup of a maths teaching space. He had started to question why there are students (in the prime of their physical life) sitting down during lessons while he (just short of requiring a Zimmer frame) does all the moving around? He had also noticed that for himself, he could do much smarter work if he did it standing at a black (or white) board and he wondered which of his students would respond similarly.
