Using inquiry-based learning, students work in groups to devise metric conversion factors after analyzing example calculations. By finding inaccuracies in the problems given, students zero in on the correct methods of doing conversions.

This lesson plan familiarizes students in grades 4-6 with using the metric system and performing conversions.

This activity can be used to introduce the metric system to learners.

Look to this site for many important numbers and conversion factors used between the metric system and the customary system, such as speed of light, body temperature, distance from sun to earth, plus more.

By the end of this section, you will be able to associate physical quantities with their International System of Units (SI) and perform conversions among SI units using scientific notation; relate measurement uncertainty to significant...

The Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill provides an interesting and easy-to-use dictionary of the history and meaning of many measurement terms. Metric, International, and...
