Explorations of problems involving the zero power are presented as routes through which instructors can take their students to reduce pupil uneasiness with the concept. Initial examination begins with routines for calculators, and discussion proceeds to more formal mathematics to generate more support for the definition of zero power. (MP)

The following ideas are presented: plans for constructing a calculator bin rack that provides a place for a school to store and charge calculators; a lesson in geometry based on a news article about salt containers; and a very simple approach to the concept of infinite geometric series. (MP)

Three methods for using four-function, counting calculators for developing understanding of the meaning of square roots and operations on whole and rational numbers are described. (MP)

How the use of calculators can illuminate mathematics and improve the level of problem-solving discussion in classes is presented. (MP)

A mathematics course using programmable calculators, which was part of a summer enrichment program for upper elementary and junior high students, is described. (MK)

Calculators are used to compute tables of values in solving problems of maximizing areas. Reproducable worksheets are included. (MP)

Investigated was the effect of availability of calculators, calculator-related curriculum resources, consultant resources, and inservice workshops on children's attitudes and achievement in mathematics (grades 2-6). Results indicated no measurable detrimental effects for calculator use. Significant gains on basic facts and achievement were made…

Exercises designed to aid students to practice or apply particular mathematical concepts and/or relationships using calculators are promoted, with four specific reasons for allowing this kind of activity. Specific cases dealing with number relationships and estimation are covered as examples. (MP)

The use of the hand-held calculator for introducing geometric growth is illustrated. The activity is designed for secondary school mathematics students. (MP)

Seven moderately and severely handicapped adolescents (mean IQ = 45) based in a regular middle school were involved in an instructional program designed to teach selected independent supermarket shopping skills. (Author)

Ten factors that can lead to a lack of use or misuse of hand-held calculators in elementary school mathematics are reviewed. (MP)

An unusual alternative starting point for instruction in a beginning calculus course that focuses on Fixed Point Iteration (FPI) is presented. (MP)

A way of exploring the concept of rational and irrational numbers with calculators is outlined. The numbers and routines suggested are designed to lead to additional extensions and provide an area for student exploration. (MP)

Activities geared to reinforcing the skills involved in solving linear equations are given. The material is prepared on worksheets designed for duplication. Student use of calculators is suggested, and the material can aid in promoting mental computation and estimation. (MP)

A study of 46 sixth graders designed to compare the problem-solving performance of pupils using calculators with that of students not using calculators is reported. The argument that calculator availability facilitates problem solving is supported. (MP)
