 Measurement Conversion: U. S. Customary

In this lesson, students start to learn how to convert measures within the U. S. Customary system.

They learn to covert a larger unit to a smaller unit. All of these conversions require multiplying the number of the larger units by the number of smaller units in each larger unit to find the number of units in the smaller measure.

Students learn to do the conversion by analyzing the problem as a multiplicative relationship like that found in application problem situations that are described in earlier lessons as the “equal groups” situation. All the units of the smaller measure are parts of the larger unit, which is the case for application problems of this type.

Students learn a systematic strategy for analyzing the problem using a multiplication table framework like that used to solve application problems based on multiplication or division.

Measurement Conversion: Metric

In this lesson, students start to learn how to convert measures within the metric system.

They learn to covert a larger unit to a smaller unit. As with the U.S. Customary System, all of these conversions require multiplying the number of the larger units by the number of smaller units in each larger unit to find the number of units in the smaller measure.

Students learn to do the conversion using the same systematic analysis and solution strategy used for converting measures in the U. S. Customary System.
