### Standard 10: Measurement

In grades K-4, the curriculum should include measurement so that students can:
• Understand the attributes of length, capacity, weight, area, volume, time, temperature, and angle
Benchmarks 9C (The Mathematical World: Shapes)
Length can be thought of as unit lengths joined together, area as a collection of unit squares, and volume as a set of unit cubes.

Benchmarks 9C (The Mathematical World: Shapes)
Areas of irregular shapes can be found by dividing them into squares and triangles.

• Develop the process of measuring and concepts related to units of measurement
Benchmarks 1B (The Nature of Science: Scientific Inquiry)
Tools such as thermometers, magnifiers, rulers, or balances often give more information about things than can be obtained by just observing things without their help.

Benchmarks 12C (Habits of Mind: Manipulation and Observation)
Determine the linear dimensions in whole units of objects having straight edges.

Benchmarks 3A (The Nature of Technology: Technology and Science)
Measuring instruments can be used to gather accurate information for making scientific comparisons of objects and events and for designing and constructing things that will work properly.

Benchmarks 9A (The Mathematical World: Numbers)
When people care about what is being counted or measured, it is important for them to say what the units are (three degrees Fahrenheit is different from three centimeters, three miles from three miles per hour).
