- The ruler is labeled "12 Inch Ruler-Halves", indicating it measures up to 12 inches and includes half-inch markings.
- Each inch is divided into two equal parts, marked by a line halfway between the whole-inch numbers.
- To measure an object, align one end with the 0-inch mark and read the marking where the other end falls.
- If the end falls on a whole number, the measurement is that many inches.
- If the end falls on a half-inch mark, add 0.5 inches to the whole number.
- For example, if an object ends at the mark halfway between 3 and 4, its length is 3.5 inches.
