Studies knowledge of young children's partitioning strategies by setting out not only to identify new partitioning strategies, but also to develop taxonomy for classifying young children's partitioning strategies in terms of their abilities. Provides taxonomy utilizing children's informal partitioning strategies as the foundation upon which to…

Investigates whether new teaching resources and minimal support could help teachers make a difference to children's understanding of decimal numeration. Indicates that teachers who used the resources achieved an educationally and statistically significant improvement in decimal understanding. (Contains 19 references.) (Author/ASK)

Both computers and calculators are limited by architecture, operating system, and software, to some predetermined level of precision within decimal number presentation and calculation. However, there exists a base that produces a terminating decimal. (MM)

Describes the use of the TI-73 calculator to support and enhance the teaching of mathematics with 9-11 year old students. Topics include equivalent fractions, algebra, and data handling. (MM)

Describes the constructs of referents, relationships, and modes and illustrates how these constructs may be reflected in students' written responses to a decimal task that requests an explanation. Examines sets of responses from two classrooms using the proposed framework to illustrate the type of information that teachers may acquire through the…

Teachers' views on practical work and their classroom practices were investigated to confirm or refute existing assumptions and literature claims. The teachers were from two primary schools in a rural area of the Hammarsdale Circuit in KwaZulu-Natal, South Africa. Questionnaires in which teachers expressed their views on practical work and…

STARS (Secondary Training for Alaskan Rural Students) materials resulted from extensive rewriting of the Vocational Adult Secondary Training (VAST) materials produced by the British Columbia Department of Education, after those materials had been used with the 9th and 10th graders on Kodiak Island. Revision was done by teachers who had been using…

Presents activities to supplement lessons on length and mass measurement or as part of a unit on atoms or orders of magnitude. Provides a lesson plan using aluminum foil to estimate unit measures, calculate the foil's thickness, and do an atom count. (MDH)

This instructor's guide consists of materials for use in helping students enrolled in postsecondary vocational or technical education programs to master pretechnical mathematics skills. Addressed in the 17 units of the guide are arranged under the following headings: Whole Numbers (whole number notation; addition, subtraction, multiplication, and…

Prepared by classroom teachers for the infusion of career education into existing curriculum, this notebook contains career-related student worksheets in a number of math skills. The activities are suitable for use with a variety of ability levels and learning styles. These worksheets for grades 7 and 8 are divided into seven major mathematics…

In the Hypothesis-Experiment-Instruction (HEI) method students are presented with a problem with three or four answer alternatives, which leads them later to recognize the distribution of choices, discuss a variety of ideas among them, and integrate distributed pieces of information. This study examined the effects of presenting a problem with or…

Fifth grade children's (n=16) understandings of simple fractions such as 1/2, 1/3, and 1/4 were investigated. The study identified three alternative conceptions of fractions: (1) 1/"N" is one of "N equal" parts, (2) 1/N is one of "N equal" parts, and (3) parts must fit together to form the whole. In addition, many…

This article presents a simple procedure to generate a sequence of rational numbers converging on the square root of 2, yielding common fraction approximations that motivate and illuminate the definition of real numbers based on rationals. Examples suggest that any irrational number can be approximated as closely as desired. A bibliography is…

A sixth-grade teacher reports an incident in which an average student discovered a complex relationship between equivalent fractions. (SD)
