Roughly speaking, there were two types of directions:
- "Take 5 steps to the right, and then move your finger up a foot."
- "Move your finger diagonally from the center for a foot."
There's some technique involved in picking points that will provoke the sorts of responses you'll want. To get talk of "diagonals," keep your point near the center of the board so that no steps are really involved. (Why? It's harder to measure inches than steps, so kids go for directions and angles.)
