A procedure is described that enables students to perform operations on fractions with a calculator, expressing the answer as a fraction. Patterns using paper-and-pencil procedures for each operation with fractions are presented. A microcomputer software program illustrates how the answer can be found using integer values of the numerators and…

Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

Developing numerical relationships with calculators is emphasized. Calculators furnish some needed support for students as they investigate the value of fractions as the numerators or denominators change. An example with Logo programing for computers is also included. (MNS)

Examples are given of how calculator-sized pocket computers, which can receive, store, and execute BASIC programs, can be used in mathematics classrooms. (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)

One schools' experiences with mathematics contests are described, with American Pi, the Great Calculator Contest, and the Forest View Math Olympics in problem solving each detailed. (MNS)

Ways of solving a problem on the connection between heat loss and the ratio of surface area to volume are described. Tables and graphs are included. (MNS)

An approach to finding the rational roots of polynomial equations based on computer graphing is given. It integrates graphing with the purely algebraic approach. Either computers or graphing calculators can be used. (MNS)

Presents an algorithm to estimate pi by approximating a unit circle with a sequence of inscribed regular polygons. Demonstrates the application of the algorithm with a hand-held calculator and an Apple computer. Provides a program to calculate pi in Pascal programing language. (12 references) (MDH)

This guide was developed to provide assistance to North Dakota schools in improving their elementary mathematics programs. Use of calculators and problem-solving instruction is firmly suggested, and computers should also be integrated in the mathematics program. Following statements of philosophy and goals, the scope and sequence of skills for…

One of five volumes intended to help teachers of mainstreamed handicapped students, the book presents twelve papers on teaching mathematics. Eight papers address instructional techniques for basic skills and problem solving: "Modalities--One Technique to Mainstream in Mathematics Instruction" (G. Rossi); "Computation Errors--Are We Treating A…

Demonstrates how the uniqueness and anonymity of a student's Social Security number can be utilized to create individualized polynomial equations that students can investigate using computers or graphing calculators. Students write reports of their efforts to find and classify all real roots of their equation. (MDH)

Activities to extend the core curriculum through the study of the periodicity of rational numbers to help students develop calculator and research skills are presented. Four worksheets are included, to be used as discovery activities. A computer program is listed, as well as examples of periodic pictures. (MNS)

Examines the potential of technology for an algebra curriculum. Provides examples of technology in use in examining families of functions, fitting a curve to a data set, and observing and analyzing patterns. Discusses exemplary software and calculators for the algebra curriculum. (MDH)

Describes a step-by-step procedure that enables teachers to develop lessons that effectively use software or special calculators in the classroom. Problem-solving strategies and questions are determined that correspond to the technology through which students are able to construct their own knowledge. Illustrates the procedure using spreadsheets,…
