This report illustrates a network of procedures which can be used to solve problems involving the addition and subtraction of fractions. This network, which is based on a skills hierarchy, is used to classify seven levels of student competency. The determination of student competency depends upon the careful construction of error-diagnostic tests.…

This module, concerned with fractional parts, contains 15 activity sheets, 12 of these involve students in making fractional parts and discovering the relationships of less than, equal to, and greater than, between different fractional parts. The last three sheets are for extending and enriching experiences with fractional parts. Teaching…

This is one of a series of student booklets designed for use in a bilingual mathematics program in grades 6-8. The general format is to present each page in both Spanish and English. The mathematical topics in this booklet include equivalent fractions, mixed numbers, and multiplication of fractions and mixed numbers. (MK)

This guide describes activities and materials which can be used in a mathematics laboratory approach for a basic mathematics program for grades 1-6. Twenty-nine activities relate to operations with whole numbers and twenty-five activities pertain to operations with fractions. These activities are described in terms of purpose, suggested grade…

Designed for the instruction of emotionally handicapped children and youth, this guide presents mathematical concepts and activities which may be utilized in outdoor education. Three authors provide three individualized resource guides on mathematics; Guide 1 deals with the concepts of measurement, time, estimation, geometry, counting, and…

The Minnesota School Mathematics and Science Teaching (MINNEMAST) Project is characterized by its emphasis on the coordination of mathematics and science in the elementary school curriculum. Units are planned to provide children with activities in which they learn various concepts from both subject areas. Each subject is used to support and…

Discusses some important components of instruction on fractions in the early childhood years. Argues that fractions should be included in the early childhood curriculum and suggests various activities and materials. (PK)

The purpose of this research was to design and evaluate a computer based adaptive strategy for teaching mathematics. Results indicated preference for materials with personalized examples for motivation and meaningful learning of problem solving procedures. Practical advantages of the computer-based model for adapting instruction are also…

Investigated was how easily pupils aged 12 and 13 who were initially unaware of the invariance of an operation (with decimals) modeling a situation could be led to such awareness. Results from clinical interviews are reviewed and a protocol presented. It appeared difficult to induce conservation. (MNS)

Examples are given of the variety of mathematical concepts and problems being studied by psychologically oriented researchers in France. Work on decimals, circles, natural numbers, decimal and real numbers, and didactic transposition are included. Comments on designing research on mathematics concept formation conclude the article. (MNS)

Difficulties that entering college freshmen showed on a mathematics assessment test are discussed. More students can perform decimal computation than can order decimals. The concept of equivalent decimals should be taught more carefully at every level. (MNS)

Presented are activities which give practice in making estimates, gathering data, and checking the reasonableness of results. (TG)
