This study investigates the effectiveness of a teaching activity that aimed to convey the meaning of indeterminate forms to a group of undergraduate students who were enrolled in an elementary mathematics education programme. The study reports the implementation sequence of the activity and students' experiences in the classroom. To assess the…

Diagrams that illustrate characteristics that are always, sometimes, or never present in a concept can be categorized as examples or nonexamples to broaden students' understanding of basic geometric concepts. (MKR)

Wallpaper is presented as a source for problems and activities involving geometry, statistics, measurement, and estimation. Sample questions and examples are discussed. (MP)

The geometry curriculum at the elementary school level is discussed. Details of five different units on geometry, each stressing space orientation, are given. (DT)

The purpose of this book is to introduce the geoboard as an effective tool that can help young children understand geometry as they develop spatial sense and mathematical thinking. Activities are clustered into three main sections: beginning geoboard explorations, exploring polygons, and coordinates. Blackline masters are included. (MKR)

This book contains materials to present mathematics concepts using cooperative learning activities. The first section explains how to make cooperative learning part of the mathematics curriculum. It includes an overview, instructions, activities for introducing cooperative learning to students and parents, guidelines for setting up groups, ideas…

An activity unit is described that helps children recognize the inside and outside of closed curves. (MP)

Topics discussed include: reasons for strategies; the use of a hierarchy of spaces from topological to Euclidean in teaching; structural strategies; pedagogical strategies; and mathematical strategies. (MP)

Planned experiences for exploration of materials are suggested for introducing geometric concepts. Examples discussed include motion, symmetry, and shape. (MP)

Activities are presented that permit students to gain firsthand experiences with ideas about two-dimensional and three-dimensional shapes and volume that textbook exercises rarely provide. (MP)

Presents three activities in which students learn about and construct star polygons using the LOGO programing lanaguage. A list of suggested extension activities is included. (JN)

Four worksheets on geometry are given. Experiences in identifying and constructing described shapes, drawing congruent polygons, and visualizing the shapes needed to build hexagons are included. (MNS)

The value and technique of pre-geometry and geometry instruction in the primary grades are discussed. Geometric concepts such as open and closed figures, connectedness, similarity, congruence, straightness, and angle are presented through suggested activities, lesson plans, and evaluation procedures. (SD)

Descriptions and pictures of apparatus for use in teaching measurement are accompanied by descriptions of typical uses of the materials. A list of names and addresses of suppliers is included. (SD)

Lists three guidelines for the sound use of manipulatives in teaching geometry. Also describes activities that use manipulatives to teach topics in geometry and measurement and which illustrate the application of the three guidelines. (JN)
