Several logical methods for dividing circles and time into legitimate metric increments are examined and discussed as being convenient for conducting business, doing mathematics, navigating, and scheduling our daily lives. (MP)

The chief pedagogical advantages of the metric system are discussed as being its coherency and an aid to learning. The reasons for converting to the metric system are discussed. (MP)

This article gives a historical background, a discussion of the International Bureau of Weights and Measures, and an introduction to the International System of Units (SI). Base, derived, and supplemental units are discussed. Prefixes, matters of form, and possible adaption problems are also considered. (LS)

Discussed is the distinction between weight and mass, and the need to distinguish these concepts in a successful metrication program. (SD)

Presented are suggestions for teaching metric conversion and the properties of quadrilaterals. (MK)

An activity is suggested which will give junior high school students practice in estimating and measuring in centimeters and millimeters. Three worksheets are given, one of which is a model for making a metric caliper. (LS)

Four articles are presented in this monthly column: dealing effectively with metric conversions; teaching how to round numbers; why a false statement implying a false statement is true--a discovery explanation; and a third-grade puzzle with interesting implications. (MP)

A problem, motivated by the conversion of Fahrenheit to Celsius, is related to classical Diophantine equations. (MK)

A discussion of the reasons for the new design of international standard typing paper (AY) with dimensions of 210 mm by 297 mm leads to a discussion of the ratio of the sides and geometric concepts involving similar rectangles. (MP)

A middle-road approach towards adopting the instruction of the metric system is presented. The realities of our cultural, economic, and political processes are taken into account and a 100 percent metric curriculum is viewed as unrealistic and anachronistic. (MP)

Described is how the faculty of a high school accepted the responsibility of helping students gain a better working knowledge of metric measures during National Metric Week. Day-by-day activities for a week are included. Eight references are listed. (YP)

This report, approved by the Board of Directors of the National Council of Teachers of Mathematics, recommends an activity-based approach to the teaching of the metric system, and lists basic objectives to be achieved by the ends of grades 3, 6, and 9. This article also appears as SE 515 577. (SD)

This section includes brief articles on holding a 'metric review show,' the 'normal' approach to graphing, graphing polynomials by using the powers of the factors, and some sum derivations. (MNS)
