Fourteen third graders were given numerical computation and division-with-remainder (DWR) problems both before and after they were taught the division algorithm in classrooms. Their solutions were examined. The results show that students' initial acquisition of the division algorithm did improve their performance in numerical division computations…

This book contains a set of versatile enrichment exercises that cover a very broad range of mathematical topics and applications in pre-algebra from the Moebius strip to the googol. Several criteria have been used in developing the activities and selecting the topics that are included. All of them bear heavily and equally on concerns for…

This textbook is part two of an arithmetic course. It provides systematic drill on oral and written exercises, and review and test questions. Attention is invited to the properties of numbers, greatest common divisor, fractions, decimals, compound numbers, business arithmetic, ratio and proportion, alligation, and square and cube root, with the…

A summary of a Human Resources Research Organization report, on the level of reading, listing, and arithmetic skills needed in four military occupational specialities and width of the gap between skills possessed and skills needed, emphasized the need for remedial literacy training and more learning-by-listening opportunities.

Estimates of children having reading disabilities range from three to 30 percent of all children in school. Is there any reason to suppose that the figure for math disabilities is any different? (Author)

Modular arithmetic is used to find the frequency of Friday 13th's in any year. (MM)

Four methods of finding the range of values of the solution of a problem when the data are known to lie within given bounds are illustrated. (MS)

After briefly presenting possible origins for the use of the decimal system for counting and the duodecimal (base twelve) system for many measures, a notational scheme using six positive'' digits and six negative'' digits is presented. Examples and algorithms using this set of digits for operations with whole numbers, fractions, and in…

Presents procedures, results, and conclusions of a research study designed to determine whether providing knowledge of results after each response on an arithmetic exercise would result in performance different from that obtained when knowledge of results is provided following completion of the exercise. The subjects were three fourth grade…

As part of their teacher training course, graduate students visited several industries to find what mathematics was in use. (MM)
