Buy-NowSq2xVoting Ruler

A ruler that enables you to vote “Yes” or “No” in lessons

Watching pupils in class it struck me how often teachers make use of hand raising as a means of assessing which pupils have understood something. It occurred to me that it might be helpful to incorporate more information in that gesture, and enable pupils to vote using a simple mechanism. By choosing which end to hold, they can do just that with the voting ruler.
