Learning Fractions in the Metric System
Date: 11/27/2003 at 12:57:02 From: Scott Subject: Metric, fractions and learning I found a website that said metric measurements should never be written as fractions. Therefore, I believe that students in countries that use fractions are at a disadvantage against students in pure metric countries. Metric students are able to bypass the subject of fractions (which confuses so many) and therefore spend time and energy on more advanced topics. Would you agree with this opinion of mine?

It is true that one is not officially supposed to write metric measurements as fractions; but I certainly hope that fully metric countries do not skip teaching fractions, because they are useful for more than just writing numbers of inches or centimeters! Knowing how to manipulate fractions is important in algebra; and fractions are the only way to write most rational numbers exactly, as well as an important model of ratios. So if anything, pure metric countries may be at a DISadvantage, in not giving students as much practice in this essential bit of math! If you have any further questions, feel free to write back. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/
