Description

A shorter version of this video is available on YouTube here: http://youtu.be/Ppg-26BYvsY The metric (SI) system of units of measurement uses powers of ten for the various units of different magnitudes. This makes converting between the units really straight forward. Talk to students about moving the digits in a number, rather than moving the decimal point, when converting. For example: 23.6 m = 2360 cm (move each digit two places to the left) Go to http://www.profpete.com to access expert resources for teaching and learning K-6 mathematics.
