Geometry and a hand-held calculator are used to find a value of pi accurate to five decimal places. (CP)

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)

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)

Describes the calculation of the potential of the Earth's gravitational field strength and the energies of satellites in orbit round the Earth with a programmable pocket calculator. (SL)

Reports results of a student attitude survey among junior high school students who had been allowed to utilize classroom calculators to check results of mathematical computations. Students displayed a significant preference for using calculators in the classroom. (SL)

Using calculators (and computers) to develop an understanding and appreciation of statistical ideas is advocated. Manual computation as a prerequisite for developing concepts is negated through several examples. (MNS)

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

Research indicates that calculators can promote mathematics achievement. Some topics with which calculators can aid are briefly discussed: problem solving, number ideas, counting, basic facts, and computation with whole numbers and decimals. (MNS)

Presented are instructions for activities in which a calculator is used to investigate algebraic concepts. Also presented are short computer programs involving topics taught in prealgebra and an activity in which a trapezoid is transformed into a circle. (JN)

The outcomes of a conference on computing in school mathematics, held in March 1984, are summarized. Recommendations on curriculum, instruction, and teacher education are included. (MNS)

This report of a March 1984 conference presents recommendations on technology and curriculum at the elementary, middle school, and secondary school levels; instruction; and mathematics teacher education. (MNS)

Ignored concepts of numbers, notation, and operation with rational numbers are described. It is proposed that these be taught in the time now devoted to paper-and-pencil skills made obsolete by calculators. (MNS)

Imaginative ways of using calculators to explore decimal fractions with secondary school and some middle school students are given. Four explorations on terminating and repeating decimals, the length of periods, and relationships are described. An appendix presents mathematical proofs. (MNS)

This article provides checklists designed to help educators select an appropriate minicalculator for their individual or groups situation. (DT)

A number-word puzzle to be solved by using a calculator is presented. (DT)
