摘要
A slope measurement and drawing aid (100) for teaching mathematics having unique indicia (130), rational-numeric slope values (184), and mathematical information (192), and a method of identifying the correct rational-numeric slope value associated with the graph of a given line, either by means of a gravity-activated indicator arm (140), or by means of the orientation of the teaching aid. For instructional purposes, when used in a classroom setting, the teaching aid can be removably held on a vertical board by magnetic (240R) or other means. When used in an individual setting, a smaller version of the teaching aid can similarly be used in a horizontal orientation on paper.
