Students must be able to find the length of objects using concrete objects, such as color tiles, unit cubes, a ruler, a yardstick, or a meter stick. Students should be familiar with both the customary (inches, feet, etc.) and metric (centimeter, meter, etc.) units of length. Students should have the basic understanding that when measuring with smaller units of length, they will have a more precise measurement when measuring to the whole unit and when measuring with larger units of length, they will have a less precise measurement when measuring to the whole unit.
