How Measurement connects to...

Measurement involves identifying an abstract spatial or temporal component of an entity (e.g., length) and comparing it to a measure unit that has the same attribute (e.g., an inch, a minute) so that the component can be assigned a numerical value, readily reasoned with, and used in calculation. Measurement is the basis for scientific inquiry and provides access to other math concepts, including estimation, fractions, and Statistical Reasoning.

### Main Ideas

Proficiency in Measurement includes:

• Understanding of unit: Knowing that all units must be the same size and that there should be no gaps or overlaps between measure units;
• Basic measurement: Being able to measure a spatial or temporal attribute using repeated standard or informal units (e.g., inches or paperclips; seconds or foot taps);
• Measurement estimation: Being able to approximate a measurable value without the use of measurement tools;
• Numerical reasoning: Being able to use formulas for measurement computations (e.g., area, volume) and converting units; and
• Measurement sense: Understanding how and why measurement works.
