Students convert between metric and customary units of length in a series of self-check exercises and timed learning games.

On this interactive site students learn to estimate lengths and distances using kilometers, explain the difference between perimeter and area, and measure the volume of a 3D object by counting the cubic centimeters.

A complete tutorial that explains time, metric system, mass, length, volume, and temperature. Interactive practices and challenge games are included.

On this interactive website students practice various math skills using a real life scenario at a school. Those skills include using centimeters and meters to compare lengths, and recognizing when a unit smaller than meters are required.

Play interactive games to explore length, perimeter, and decimals.

Students will complete a series of learning games to explore measurement such as length and volume.

This site from the Math Forum is a great introduction to measurement for primary students. Each measurement activity has four components: interactive, manipulative-based project; technology; paper/pencil practice; literature connection.

A guide to support parents as they work with their students in unit conversions and problem solving with metric measurement.

This site contains an extensive list of various units of measurement known internationally and across several disciplines. Unit symbols are also included.

Very complete chart of conversion factors for English to SI (metric) unit measurements and SI (metric) to English unit measurements. Includes length, area, volume, mass, temperature, illumination, and force & mass (stress).

Students learn the metric units engineers use to measure mass, distance (or length) and volume. They make estimations using these units and compare their guesses with actual values. To introduce the concepts, the teacher needs access to...

Metric units of length (millimeters, centimeters, meters, and kilometers) are reviewed and practice problems are provided.

Convert distance measures between the English (inches, feet and yards) and metric (mm,cm,meters,km). It is intended to help with both your math skill and your understanding of the metric system.

Second graders will use their addition and subtraction strategies to measure and compare distances, solving using centimeter units.

Practice estimating the length of real life objects using metric units. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This metric system tutorial is compared to the U.S. standard system so that students can comprehend the measurement of length, volume, mass and the like.

Students rotate from station to station completing activities involving measurement weight, length, and volume using metric measurement.
