Overview

In fourth grade, students will use the metric system to measure length, mass, and capacity. Students will learn what unit is appropriate for each measurement and this can be challenging. This video is a point of reference when learning conversions.

Knowledge

Students know:
  • units of measures for given attributes vary in size and are related by multiplicative comparison.

Skills

Students are able to:
  • Select and use appropriate units of measure for a given attribute.
  • Convert larger units of measure to smaller units of measure within the same measurement system.
  • Record measurement equivalents in a two-column table.

Understanding

Students understand that:
  • There is an appropriate unit of customary measurement and metric measurement for a given attribute.
  • Multiplicative relationships exist between customary units of length, mass, liquid volume, and time.
  • Multiplicative relationships exist between metric units of length, mass, liquid volume.
