Applies the Lesh Translation Model to develop conceptual understanding by showing relationships between five modes of representation proposed by Lesh to learn multiplication of fractions. Presents five teaching activities based on the translation model. (MDH)

Performance assessment, a method that makes possible the assessment of multiple dimensions of students' progress, including dispositions, is described. Criteria for good performance tasks are given, and their structure is illustrated through an example. A list of 10 dispositions toward mathematics and a self-evaluation group-performance rating…

Presents a program to introduce fifth graders to everyday economic life by constructing a true-to-life simulation of an economic community. Students apply mathematics skills to managing a checking account, calculating electric bills, and managing shops using computers. (MDH)

Arrays are seen as excellent models for beginning multiplication examples, but that they are often put aside by teachers when they become unwieldly for greater factors, possibly depriving learners just when they need the help. The use of grids made on paper marked in squares is suggested. (MP)

A fifth- and sixth-grade project is described that requires each student to build a bridge to specified dimensions using only specified materials. (MK)

Discusses: (1) different types of learning (concepts, properties, facts, procedures, algorithms, skills, and problem solving); (2) types of learning behaviors; and (3) types of representational models, considering concreteness, meaningfulness, and manipulation (active manipulation, passive manipulation, and nonmanipulation). (JN)

A model of the division algorithm is described which relates step-by-step to the standard algorithm. Use of the model in instruction requires the distribution of a special worksheet. The focus of the instruction is on students sharing some amount of money equally among several friends. (MP)

The process of metrication is seen ultimately to require a grass-roots movement to change traditional behavior patterns. The creation of metric leaders is viewed as a tool for speeding the process of acceptance. A model for the design and execution of leader-training sessions is detailed. (MP)

Use of prepartitioned models is proposed to help students construct a meaningful concept of fractions. Partitioning, geometric shapes as fractional models, concepts related to successful partitioning, and other benefits from partitioning experiences are discussed. Sample activities are suggested. (CW)

The use of a computer software package called "Exploring Measurement, Time and Money--Level 1" to help children explore many different arrangements of data and the effects of changing that data is presented. Activities which may be used to prepare students for this instruction are described. (CW)

Describes a concerns-based approach to professional development programs designed to implement current reforms in mathematics education. Identifies seven Stages of Concern and includes a table of typical statements, expressions of concern, and intervention strategies a change facilitator can follow with teachers at each stage. (MDH)

Describes a professional development program to train math/science specialists for the upper elementary school grades. Using results from an interest survey, 30 teachers were chosen to participate in a 3-year program to become math/science specialists. Presents the teaching model used and the advantages for teachers and students in having subject…
