The author has selected a number of episodes that illustrate some of the successes and failures of humanity's attempt to find the area of the circle and presents them as problem studies. (MN)

The author gives a variety of literary questions and exercises that can be used to develop and test students' interpretation of the mean, median, and mode and their understanding of the usefulness and limitations of each. (MN)

An elective course aimed at giving tenth-grade students some experience with practical arithmetic problems is outlined. The two-week course is designed primarily for students who will be leaving at the end of the year and includes topics such as calculators; earning, spending, and saving money; tax; and buying a car. (MN)

Provides four pages of practice problems covering the skills of multiplication, addition, and subtraction. Follows the premise that many arithmetic operations be done in working toward a solution. The sheets could be photocopied as worksheets or handouts. (JM)

The use of trial-and-error strategies to solve problems is endorsed. Types of problems with which trial and error is effective are discussed, with examples of how it is used, and teaching considerations are briefly considered. A computer program for one problem is included. (MNS)

This booklet contains the teacher's guide to a mathematics placement test which was developed to assist teachers in providing the best match between instructional materials and student needs. It covers math skills from whole numbers to algebra. The placement test is divided into six parts, each consisting of 10 to 22 problems, and is based on exit…

Groups trained to compare the whole and subset improved in cue identification from negative instances; performance in the stimulus exposure group declined. (Authors)

This heat transfer problem requires students to analyze the feasibility of moving icebergs from the Antarctic to Saudi Arabia to provide fresh water. (BB)

This problem requires the student to calculate the volume of air breathed by a bicyclist every hour in Denver, Colorado, and New York City. (BB)

"Mental work" recorded in primary mathematics classes as part of the Classroom Interaction Process is not a simple, single activity of drill or quiz but a set of overlapping activities with different functions. A more analytical approach to mental work is advocated to enhance its usefulness as a classroom activity. (Author/SJL)

Two problem-solving posters with a Halloween theme are included. These activity sheets are designed to be easily reproduced for classroom use. (MP)
