This is a series of four units introducing the concepts of solids, faces of solids, points, lines, and planes. Emphasis is placed on the discovery approach with a maximum of manipulation and experimentation on the part of the children. Each unit has suggested activities that include games, individual projects, worksheets, and discussion questions.…

This instructional unit seeks to prepare the student to exhibit competence in the mechanics of measuring and estimating angle size and in making generalizations on the nature of measurement. Experimentation with the use of circular and semi-circular protractors is encouraged. Exercises and discussion questions are given for each section.…

This guide to accompany "Geometric Excursions" contains all of the student information in SE 015 344 plus additional teacher materials. With each section are listings of objectives, equipment and teaching aids, suggested approaches, and discussion questions. Masters are provided for making transparencies and student copies of patterns…

Describes the Boston Public Schools Recycle Center which receives materials donations from more than 100 local industries. These donations are used as educational materials for disadvantaged pupils. Materials are free and teacher training workshops are provided. Ecological implications for urban students and teachers are discussed. (PS)

Discussed is the difference in the use of verbal explanation, identified by observations of mathematics teaching in first- and fifth-grade classrooms in Japan and the United States. The author suggests we reexamine the role of direct teaching and stress both concrete experiences and verbal explanations at the same time. (MNS)

Presented are two sets of materials appropriate for exploring different aspects of shape. Ideas about sequences are considered. (PK)

This study investigated the ways students represented fractions on number lines and the effects of instruction on those representations. The instruction primarily concerned representing fractions and ordering fractions on number lines. (Author/PK)

Presents a rationale and activities for using teacher-made laminated strips to teach fraction division concepts. (PK)

Two teachers share practical tips for teaching secondary school mathematics. The tips focus on effective use of homework and teaching trigonometric concepts. (PK)

This study investigated the effects of combining interactive microcomputer simulations and concrete activities on the development of abstract thinking in elementary school mathematics. Students in grades 2-4 were assessed on tasks involving designs and patterns. (MNS)

Building projects with blocks provide opportunities to foster creative thinking skills. The connection between blocks and thinking how to implement the strategy are included, along with examples. (MNS)

Research on fractions and decimals is reviewed. Understanding is vital, and thus children need experiences with concrete materials for the various interpretations of rational numbers. (MNS)

Algebra is one of the top priorities of mathematics instruction for the elementary and middle grades. This book is designed to help K-2 teachers meet the challenge of making algebra an integral part of their mathematics instruction and realize both what to teach and how to teach central algebraic concepts. Classroom-tested lessons help teachers…

The objective of this intervention guide is to prepare each student to be mathematically literate to survive in a world that is changing and growing as technological advances are creating new applications of geometry, measurement, statistics, and counting procedures. It accomplishes this goal by providing an intervention setting that includes…

This guide is a collection of ideas for mathematics activities which were assembled and tested by primary teachers. Activities are correlated to a mathematics curriculum for ages 7-9 years. The activities supplement the teaching of basic numeracy and include topics such as the language of mathematics, matching numbers, tracing the numbers, number…
