The author discusses factors to consider when choosing a hand calculator power supply, size, functions desired, range and accuracy, amount of use, and display. (SD)

A calculator intervention produced a marked increase in correct computational performance of eight educable mentally retarded adolescents over baseline for addition, subtraction, multiplication, and division problems. Use of calculators enabled Ss to complete relatively complex arithmetic problems with greater accuracy than nonhandicapped Ss…

Describes the development of computers and calculators, noting intitial resistance to and later acceptance of calculators in the classroom. Advocates teaching children to perform simple calculations and stresses estimation skills over speed and accuracy for doing long, complicated computations. Includes recommendations for classroom calculator use…

Two games and one activity designed to be used with a hand-held calculator are presented. (MK)

Deals with the conversion of electronic hand calculators to timing devices. This article illustrates a conversion of a rather versatile calculator by means of simple and inexpensive circuitry. (HM)

Ways of using the calculator as a vehicle for investigating one aspect of the square root concept are illustrated. (MK)

An example is given of a class of problems whose solutions require the use of a scientific calculator in order to plot the graphs. (MP)

Described is an activity demonstrating how a scientific calculator can be used in a mathematics classroom to introduce new content while studying a conventional topic. Examples of reading and writing large numbers, and reading hidden results are provided. (YP)

Discusses the history of different methods of representing numbers and how these representations facilitated counting and computing devices such as the abacus. (MDH)

Found that, after extracting an arithmetic problem from a real situation and working out an answer, 6- to 12-year-olds with learning difficulties in math were unable to reapply the answer to the situation. Also found that the children, in a hypothetical situation, were unable to use token money, or to do calculations on paper or with an electronic…

Analyzes and refutes the arguments made by "back-to-basics" proponents against the use of calculators and for traditional instruction in the algorithms of pencil-and-paper arithmetic. Argues for the value of mental arithmetic in achieving all the aims and more of the traditional curriculum. (Author/ASK)

Indicates that the calculator as a tool has an assured place in science teaching and gives examples of its use. Evaluates 18 different calculator models. (GS)

Designed for use by students at beginning high school through adult levels, this manual contains seventeen lessons on uses of the electronic hand calculator. Within each of the eight sections lessons presented include objectives, procedural information, examples, and problems to be solved. Following an introductory lesson to the calculator,…

Described is a calculator race that is designed to require a fast touch with the calculator and also the ability to apply mathematical knowledge. Sample questions are given. (MP)

Repeatedly taking the square root with a calculator yields numbers with logarithmic-type properties, which can be used to define the logarithm functions. (MP)
