This paper demonstrates how calculators may be used to motivate a concept called infinite composition of functions. Several mathematical topics, such as continued square roots, continued fractions, and infinite products are treated and discussed as special cases. (Author/MK)

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

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,…

Included are a detailed example of a calculator demonstration, the general principles to be followed in preparing a calculator demonstration, a list of demonstration topics for a calculus course, and some suggested topics for other courses. (MK)

A community college mathematics course is discussed in terms of type of student, content and goals. Particular attention is given to the role of the calculator in community college remedial mathematics courses. (MK)

The author discusses the use of calculators in calculus classes and difficulties caused by roundoff errors. References for advanced follow-up topics are given. (Author/MK)

Two posters that can provide simulated problem-solving experiences at a corner store are provided. (MK)

Four problems are presented and solutions using a calculator are illustrated. (MK)

Suggests a number of guidelines to serve as a basis for policy on the use of hand-held calculators in the elementary school. (MP)

Several examples are given to show that the calculator can be a tool to enhance mathematical understanding. Expressing rational numbers (fractions) as decimals provides the content focus. (MNS)

Worksheets designed to help students explore factoring integers are presented. (MP)

An experimental program using the calculator in third, fourth, and fifth grades is described. Three example lessons are included, on (1) subtraction with regrouping, (2) estimation, and (3) number theory: Quadratics. (MK)

Examples given for uses for the calculator exchange key include: generation of the Fibonacci sequence and geometric series, determination of square roots, and the chief use of the function, which is to interchange the numerator and denominator of a fraction. (MK)

The format of digits in liquid crystal displays (LCDs) on calculators and watches can motivate some simple investigations appropriate for school mathematics. Several sample problems or investigations are provided. (MK)

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)
