Twenty-two seventh and eighth grade students poor in mathematical computation but with average reading comprehension (low math group) were compared with two matched groups: low reading group and no difference group. It was concluded that children with a disability in mathematical computation may be at risk for impulsive and possibly antisocial…

The Euclidean algorithm for finding the greatest common divisor is presented. (MNS)

Describes the history, development and classroom uses of Chisanbop (finger numerals). Cites the results of research utilizing first grade mathematics classes, half using Chisanbop, half not, the Chisanbop group making significantly higher scores on the Iowa Basic Skills Test of computation than the control group. (DS)

Three experiments evaluated performance on a mental multiplication task and the adequacy of several different models of mental addition as extended to multiplication. Results are discussed in terms of a network-retrieval approach to mental arithmetic, the commonalities between addition and multiplication, and rule- versus retrieval-based…

Describes a program written in BASIC, called BIGNUM, that was designed to aid in handling big numbers. The program adds, subtracts, multiplies, divides, and raises to a power integers of up to 1024 decimal digits and is thought to be usable on many types of machines. (MP)

Sixty children aged 2-3 to 5-6 were given four quantity tasks that tested their understanding of "more" and "same." Tasks involving a manipulative response were significantly easier than those involving a yes/no judgment. (Author/RH)

Suggests that ordinal and ratio criteria for equity are independent of one another, but that a plausible mathematical definition of equity must satisfy both criteria under all outcome/input ratio situations. Demonstrates that a modification of the Harris linear formula for equity meets these criteria. (Author/RD)

This article estimates to what extent changes in the unemployment rate over the past two decades have reflected basic cyclical factors in the demand for labor and to what extent they may stem from noncyclical factors. (BM)

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)

Twenty-eight sources on calculators are listed in this partially annotated bibliography. (MK)

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)

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)

An activity is described for introducing some fundamental notions in inferential statistics to students in elementary high school statistics courses. (MP)

A description is given of an approach to teaching a remedial mathematics course using calculators as a complete substitute for paper-and-pencil calculation. (MP)
