There are two systems of measurement, and in this lesson we're focusing on the "metric system". If you're looking for an introduction to the metric system, or you're confused about how large a gram or a meter actually is, then this is the perfect place to start! We'll go over the prefixes used in the metric system, the base units for measuring mass, volume, and length, and talk about some examples of those measurements in the real world. The metric system isn't just for science class; come along with us as we learn about this system of measurement in today's MightyOwl lesson!
