Measurement
Instructional programs from prekindergarten through grade 12 should enable all students to--
- understand measurable attributes of objects and the units, systems, and processes of measurement;
- apply appropriate techniques, tools, and formulas to determine measurements.

The study of measurement is crucial
in the pre-K–12 mathematics curriculum because of its practicality
and pervasiveness in so many aspects of everyday life. The study of measurement
also provides an opportunity for learning about other areas of mathematics,
such as number operations, geometric ideas, statistical concepts, and
notions of function.
Measurement is the assignment of a numerical value to an attribute of an object. In the earliest grades, students can compare and order objects using language such as longer and shorter. As they progress through the grades, students' collection of measurable attributes, their understanding of the relationships among attributes, and their understanding of precision in measurement should expand. By high school, for example, students should recognize the need to report an appropriate number of significant digits when computing with measurements.
