### BIG IDEAS

So that I can determine my weight to know if I am growing in a healthy way.

So that I can determine how much space an object takes up.

### UNDERSTANDING THE STANDARD

- The concept of a standard measurement unit is one of the major ideas in understanding measurement. Familiarity with standard units is developed through hands-on experiences of comparing, estimating, measuring, and constructing.
- Benchmarks of common objects need to be established for each of the specified units of measure (e.g., the liquid volume of a small glass of orange juice is about one cup). Practical experiences measuring the volume of familiar objects help to establish benchmarks and facilitate the student’s ability to estimate measures.
- One unit of measure may be more appropriate than another to use when measuring an object, depending on the size of the object and the degree of accuracy desired.
- Correct use of measurement tools is essential to understanding the concepts of measurement.
