These clever 6" rulers were designed by a teacher whose students were initially experiencing difficulty conceptualizing halves and fourths when first learning to measure lengths using customary/household units. In place of plain hatch marks, each inch is divided into whole-, half-, and quarter-inch rectangles. To avoid the confusion a lot of elementary school students experience when using standard rulers, the beginning of the first inch coincides with the starting end of the ruler, and because the natural inclination of most of his students was to measure items vertically as opposed to horizontally, the inches are numbered vertically as well. The rulers can be printed on card stock and reinforced with transparent shipping tape before cutting, or laminated if desired. Each sheet yields seven 6" rulers.
