Grade 2 Measurement and Data

2.MD.A.2

Full Standard

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.

About the Math

Skills and concepts below are learning goals for this standard.

  • Determine appropriate units of length (e.g., inches, feet, centimeter, meter) to measure an object.
  • Measure an object with two different unit lengths (e.g. inches and feet).
  • Explain how the size of the unit length affects measurement (b/c inches are smaller than feet, one will need many more inches to measure something large).

Measurement is a number that indicates a comparison between an attribute (length) and the same attribute of a given unit of measure. We match the object being measured with the standard unit. Use both centimeters and inches to measure length. Students should use two different units of length measurement, such as inches and centimeters, and be able to describe how the difference in units affect the measurement they found. Essential vocabulary for this standard includes: length, unit, centimeter, inch, and nonstandard measurement. Visit the online dictionary Links to an external site. for vocabulary support.
