Measuring in Customary Units
Measurement is the most commonly used mathematics application, particularly in the study of science. Children need to do the following things in order to build understanding of measuring.
* Know what can be measured or what are measurable attributes, such as length and time.
* Use non-standard units but understand why standard units must be used.
* Choose the appropriate unit, tool, and technique to measure the attribute.
* Estimate and then compare the estimate with the actual measurement.
* Understand that measuring an object is an iterative and counting process.
* Know that choosing a unit, placing units repeatedly with no gaps or overlaps to fit the object, and counting how many units it takes results in the measurement of the object in that unit.
* Connect measurement with number and operations.
* Compare and order objects according to measurable attributes.
