Many have argued for the importance of numeracy, yet little is known about the opportunities for numeracy available to people in their daily lives. In this study, characteristics of rational numbers in magazines written for children, teenagers, and adults were analyzed and compared. Analysis indicated that difficult mathematical concepts that…

This book presents teacher-written cases relating stories, insights, and experiences about the teaching of fractions, decimals, ratios, and percents. The cases were written to stimulate colleagues to examine their own practice, to think hard about the mathematics they teach and would like to teach, and to initiate inquiries and discussions that…

This document is part 1 of the workbook for grade 6 pupils in the Comprehensive Instructional Management System, a unified mathematics curriculum for kindergarten through grade 7. Each objective is developed by a variety of strategies, with mastery of objectives diagnosed through a testing component. The activities in the student workbook are…

This discussion of cyclic patterns that appear in repeating decimals includes the use of the calculator in discovering the patterns. (MP)

These four books are intended for use by individuals who need numeracy instruction as well as by those who help such individuals. Explanations are offered of how to do a large variety of calculations; different methods of getting the right answer are also provided. Book 1 focuses on numbers, how they are written, what they mean, how they are…

Students make errors in mathematics for a variety of reasons. It is the job of the educator to identify the source of these errors and to assist students in correcting them. The purpose of this monograph is to help identify, analyze, and evaluate students' computational proficiency. This monograph is divided into four sections: "Whole Numbers";…

This teacher guide is part of the materials prepared for an individualized program for ninth-grade algebra and basic mathematics students. Materials written for the program are to be used with audiovisual lessons recorded on tape cassettes. For an evaluation of the program, see ED 086 545. In this guide, the teacher is provided with objectives for…

Discusses procedures used throughout history to solve fractional and decimal divisor problems. Early rules and definitions, approaches in mathematics and methods books, "new math" approaches, research findings, and recent textbook procedures are included. Concludes by presenting nine recommendations for teaching the operation. (DH)

Both general and specific effective strategies for teaching decimals, fractions, and percents to students with learning disabilities are presented. Information is provided on the theoretical base that underlies these curricular areas, recent research, and future trends. The need for programs to be structured around individualization and intensity…

While no harmful effects result from the study of nondecimal arithmetic in the elementary schools, it is possible that a disproportionate amount of time is being devoted to this type of learning. (CK)

Two enrichment articles are presented; one dealing with finding partial fractions and reducing to polynomials; the other, with finding the heaviest object from eleven others of equal weight where all twelve are identical in appearance. (JG)

The links between decimals and various types of progressions are explored. Special attention is given to geometric progressions. (MK)

Discusses how well children (N=6) who have had instruction in rational-number concepts based on a continuous manipulative aid are able to transfer their knowledge to accomplish tasks based on a manipulative aid which can be interpreted as discrete. Suggests several implications for teaching fraction concepts to children using continuous and…

Describes "fraction flags", an activity through which fraction concepts can be explored. The activity was invented by 2 12-year-old students and this article is presented with emphasis on the students' viewpoint. It begins with an overview of the fractions unit and presents vignettes of students exploring the fraction flags. (AIM)
