This article summarizes research conducted on calculator block items from the 2007 fourth- and eighth-grade National Assessment of Educational Progress Main Mathematics. Calculator items from the assessment were categorized into two categories: problem-solving items and noncomputational mathematics concept items. A calculator has the potential to…

Illustrations are provided which show how some algebraic manipulations done prior to doing calculations can eliminate unnecessary storage of data, reduce the total number of needed steps, and avoid overflow. (MN)

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)

Comparing calendar years and planetary years serves as the basis of a calculator problem. (MP)

Described is the calculator's place in the classroom and its potential for reshaping our computationally oriented curriculum. Activities are suggested for ways calculators can effectively be used to develop four types of mathematical thought. (Author/DS)

The article seeks to illustrate that calculators and problem solving complement each other perfectly. (MK)

A discussion is given of calculators in the classroom. Opinions and recommendations of various groups are incorporated. (MK)

Instruction of three children using calculators for a ten-week period resulted in achievement gains. (MNS)

Suggests and illustrates ways in which systematic consideration of selected unary operations can be facilitated by using electronic calculators. Emphasis is placed upon unary operations suitable for exploration and investigation at the pre-algebra level, using calculation algorithms as a basis for generating examples and non-examples to develop…

This study compares a pencil-and-paper drill strategy with a calculator drill strategy in facilitating the learning of multiplication facts. The results suggest pencil-and-paper drill is more effective. (MK)

Five calculator activities are described that are designed to explore ordered operations. Suggestions are given on mathematical objectives, strategies for solving, and possible extensions or follow-up activities. (MP)

The objective were to explore some of the ways in which the calculator can be used and to determine the effects. Areas covered are: computation, mathematics readiness, problem solving, and discovery learning. (MP)

Presents a study in which a group of 25 undergraduate students was given seven whole- or decimal-number estimations and asked to determine the exact answer using a calculator programmed to give incorrect answers. Points out subjects' lack of confidence in their estimation skills as well as a reluctance to question calculator-produced results.…

A program utilizing minicalculators in a mathematics class at the eighth grade level is described. The recommendation is made that the utilization of calculators not exceed one experience per week. (MN)

Research on the usefulness of calculators in mathematics instruction is cited, and some activities using calculators to develop skills with reading numbers, counting, basic facts, multiplication and division, problem solving, estimation, percentages, decimals, patterns, probability, and games are described.
