Choosing the Best Measuring Tool for Length 2-115

Use benchmarks to develop a sense of length. Measure your arm to know which part is 12 inches – the length of a ruler. Measure your height to know which part of your body is 3 feet tall – the length of a yardstick. Which tool do you use to measure a pencil? It's shorter than your forearm, so a ruler. An umbrella? It's longer than your forearm so a yardstick.
