About This Worksheet

This medium-level worksheet contains 14 problems designed for 3rd Grade students practicing measuring length. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Measuring length in both systems builds flexibility and prepares students for science, where metric units dominate, and everyday life in the U.S., where customary units are common. Understanding both systems develops proportional thinking.

  • Measure and estimate lengths in both metric and customary units
  • Choose the appropriate unit for a given measurement
  • Convert between related units (e.g., feet and inches)
  • Use a ruler to measure to the nearest quarter inch and centimeter
  • Solve problems that require adding or subtracting lengths with units
