The lesson described first involved tossing a pair of dice and recording on a graph the sum produced on each roll. Pupils examined questions such as which sum occurred most often. The second part involved a graph that indicated which types of sums were most likely to occur. (Author/MP)

The use of microcomputers to aid geometry instruction is emphasized through discussion of a program written in BASIC which provides for experimenting with polynomial curves. The program listing is included. (MP)

Describes how to use certain action research methods to increase researchers' access to intergroup relations embedded in organizations. Discusses studies using these methods in two corporations--one on work group relations and the other on race relations among Black and White managers--and notes implications for intergroup relations theory.…

Several methods of numerical mappings other than the usual cartesian coordinate system are considered. Some examples using parallel axes representation, which are seen to lead to aesthetically pleasing or interesting configurations, are presented. Exercises with alternative representations can stimulate pupil imagination and exploration in…

Five reasons why graph work is effective are given, followed by suggestions for making bar, picto-, and line graphs. (MS)

Describes work performed under the Spelling Error Detection Correction Project (SPEEDCOP) at Chemical Abstracts Service to devise effective automatic methods of detecting and correcting misspellings in scholarly and scientific text. The trigram analysis technique developed determined sites but not types of errors. Thirteen references are listed.…

A hungry worm is looking for something to eat according to very specific rules, and the path he takes is a graph. The problem is detailed in Applesoft BASIC using low resolution graphics for worms that turn 90 degrees and high resolution for worms that can turn 45 degrees. (MP)

A program developed by a high school freshman is presented that plots unusual graphs on the screen of a TRS-80 computer. The view promoted is that teachers of advanced mathematics should not be surprised if new ways of looking at the subject come from students interacting with computers. (MP)

A teaching experiment to evaluate the language approach to learning graphical interpretation is described. A series of experiments using a science laboratory were described using either tables or graphs and the approaches contrasted. (MP)

The article discusses the experiences of the writer when using simple surveying as a practical topic with secondary school children. (Author/MK)

Described are graphing activities which can be instrumental in introducing the mathematics concepts of counting, sorting, grouping, and comparing on the primary level. On the intermediate level, these activites can be used to introduce collecting and sorting unorganized data, and creating graphs to represent the data. (Author/TG)

Worksheets designed to aid in the instruction of graphing on the Cartesian coordinate system are presented. Finding areas and perimeters of polygons the pupils graph are the intended lesson topics. (MP)

The process skills discussed include: observation; estimation; communication; mensuration; and graph construction and interpretation. Two activities for grade 6 and beyond are suggested. (MK)

Directions are given for making a model of a three-dimensional coordinate graph. (DT)

Describes a technique that uses cellular telephones and their rates to enliven the topic of linear equations in a college algebra course. Uses mathematics to select a cellular telephone plan from a vendor. Enables students to use and connect the ideas of functions, equations, graphs, and applications. (DDR)
