Understanding Metric Units and Measurements

This lesson teaches how to recognize common units of measurement by comparing them to everyday objects and events. It covers the US customary system, which is complex due to varied units and fractions, and the metric system, which is based on units of 10 and is widely used for its precision. The lesson explains metric prefixes like kilo, centi, and milli, and addresses common misunderstandings between metric and US customary units. It also details metric length and volume units, and discusses time measurement in both systems.
