Videos, examples, lessons, and solutions to help Grade 2 students learn to 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.

Common Core: 2.MD.2

Suggested Learning Target

  • I can select several appropriate units of length (e.g., inches, feet, centimeter, meter) to measure an object.
  • I can accurately measure an object with two different unit lengths.
  • I can compare the measurement using the shorter unit length to the measurement using the longest unit length, and explain how the size of the unit length affects the measurement.
  • I can recognize the equivalent units of 12 inches = 1 foot and 100 centimeters = 1 meter as well as non- standard equivalent measurements
