options: Estimate lengths using units of inches, feet, centimeters, and meters.

Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.

Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.
