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)
Grades 3-5, page 223
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)
Grades 3-5, page 223
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)
Grades K-2, page 10
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)
Grades K-2, page 293
Determine the linear dimensions in whole units of objects having straight edges.

Benchmarks 3A (The Nature of Technology: Technology and Science)
Grades 3-5, page 45
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)
Grades 3-5, page 212
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).

Benchmarks 9A (The Mathematical World: Numbers)
Grades 3-5, page 212
Measurements are always likely to give slightly different numbers, even if what is being measured stays the same.

• Make and use estimates of measurement

Benchmarks 12B (Habits of Mind: Computation and Estimation)
Grades K-2, page 290
Make quantitative estimates of familiar lengths, weights, and time intervals and check them by measurements.

• Make and use measurements in problems and everyday situations

Benchmarks 12C (Habits of Mind: Manipulation and Observation)
Grades 3-5, page 293
Measure and mix dry and liquid materials (in the kitchen, garage, or laboratory) in prescribed amounts, exercising reasonable safety.
