The development of square units for area and cube units for volume is discussed with emphasis that switching focus from one physical property to another is involved as opposed to simply multiplying units. (MN)

One method is described for supplementing the assignment of theorems to be proved, involving student grading of purported theorems with alleged proofs for correctness and clarity. (MN)

Some misconceptions about "squares" encountered among college students as they attempt to master appropriate subject matter in preparation for teaching elementary grades are presented. (MN)

A course in reading, evaluating, and using educational research taught to inservice mathematics teachers in the Emory University Master of Arts in Teaching program is described. (MN)

The authors present a computational skills laboratory exercise for ecology conscious students. (MN)

An activity unit is presented in which the minicalculator is used in determining the student's paces or steps per kilometer and their measuring distances. (MN)

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)

This module was prepared to "metricate" approximately 3800 teachers in Western Kentucky. A brief history of measurement systems is followed by sections concerning length, mass (weight), temperature, and area and volume measurement. Each section contains a list of the common metric units used and their relationship as well as activities…

A classroom activity is illustrated in which vectors are drawn in the first quadrant of a rectangular coordinate system forming a vector polygon which is then reflected about each axis. (MN)

An exercise is presented for the purpose of understanding and determining area which involves using a balance as opposed to algorithms or computation. (MN)

The authors propose that electronic calculators can be perceived as function generators rather than mere computational aids and can be used to investigate function concepts such as domain, range, composition, inverse, correspondence and so on. (MN)
