Different regular-polygon-shaped candles wound with a sheet of paper are cut through obliquely. When the papers are unwound, unique patterns are revealed. Investigation of these patterns leads to the discovery of geometric concepts. (JP)

Homemade geostrips, "angle-fixers" (cardboard circular sectors) and brass fasteners can be used by students to explore properties of angles, triangles and other polygons. Several games and other activities are suggested. (SD)

This document begins with a discussion of the author's approach to instruction in a mathematics laboratory. This discussion includes an enumeration of types of desirable or necessary equipment and advice on the management of a laboratory. The author examines issues related to achievement and readiness for more traditional school experiences in…

Discusses the ways in which young children's minds can be engaged through play with a variety of manipulative objects and experiential activities in the day care environment. Such engagement encourages children's thinking and increases awareness and understanding of the world. (NH)

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.…

Presents three hands-on, discovery geometry lessons based on the use of special pieces called Polydrons by a fifth-grade class to build and investigate special properties of polyhedra and to stimulate students to think geometrically. Includes reproducible student worksheets. (MKR)

Presents a series of lessons that extend the concrete experiences many elementary students have had with attribute blocks to provide middle school students with informal opportunities to explore the concepts and properties of relations and functions. (DDR)

This publication reviews the mathematical laboratory from three perspectives: a practical view of laboratories in operation, a review of related research, and a view of current laboratory evaluation procedures. After a discussion of definitions, types, and purposes of math labs, the first paper concentrates on their historical development in…

This book is designed as a report and an in-service tool for teachers of grades K-6. It is built around the idea that the standard textbook treatment of metric measurement gives rise to many misconceptions among primary grade children. This report is a record of the development of alternative methods for introducing measuring activities to…

Described are many concrete readiness activities within ten broad categories that are designed to provide children with a solid foundation for mathematics and that help prevent learning difficulties in mathematics. Preschool mathematical experiences form the foundation for all studies in mathematics. Without a sufficient number of appropriate…
