Measuring Length

1.7 Measurement. The student directly compares the attributes of length, area, weight/mass, capacity and temperature. The student uses comparative language to solve problems and answer questions. The student selects and uses nonstandard units to describe length.
  • 1.7A Estimate and measure length using nonstandard units such as paper clips or sides of colored tiles
  • 1.7C Describe the relationship between the size of a unit and the number of units needed to measure the length of an object

Core Components:
  • Directly compares the lengths of two or more objects.
  • Determines which object is longer (or shorter) and provides explanation justifying response.
  • Uses comparative language such as longer than, shorter than, longest, shortest, same length.
  • Selects non-standard units that have the attribute of length to measure objects.
  • Uses visual estimation as well as guess-and-check strategies to determine lengths of objects in non-standard units.
  • Identifies objects that have equal length.
  • Begins to measure at the edge of the object being measured.
  • Lines up non-standard units end-to-end with no gaps or overlaps.
  • Uses a variety of sizes of objects (units) to measure the same object.
  • Understands that if you measure an object with a small unit (cm cube), it will take more of them to equal the length of an object than if you used a larger unit (color tile) to measure with. Ex: It takes 12 cubes to equal the length of a pencil, but only about 5 color tiles.

Vocabulary: unit, non-standard unit, customary, size, length, yard, foot, inch

Can you describe or demonstrate the attribute of length?
Why do we measure length?
What is the relationship between length and distance?
What data (information) do we get when we measure length and how do we use it?
What nonstandard units with the attribute of length can be used to measure the length of an object?
How does the size of the unit of measurement affect the number of units needed to measure the length of an object?
