Presents mathematics activities focusing on explorations in the environment that include visual or geometric components. (ASK)

Dissection work with two-dimensional shapes is discussed, and patterns to be copied are given on three worksheets. A fourth worksheet contains instructions for pupils to make their own shapes and dissect them. (MNS)

Suggests discovery activities in spatial awareness for elementary math, utilizing home-made geometric shapes and soma cubes. (SJL)

Describes seven spatial abilities related to mathematics including eye-motor coordination, figure-ground perception, perceptual constancy, position-in-space perception, perception of spatial relationships, visual discrimination, and visual memory. Discusses the relationship of the spatial abilities to the study of geometry. Lists 19 references.…

Discusses the importance of using children's previous experiences with geometric figures to build foundations for developing geometric thinking. Describes how children's play with unit blocks can be structured to give them experiences with geometric concepts. Contains 12 references. (ASK)

Calculus students have great trouble visualizing solids of revolution and their cross sections. Illustrates the use of props in order to help students understand the solid revolution. (ASK)

Describes how to deal with students' structuring of rectangular arrays of squares and other two-dimensional regions. Presents activities that connect spatial structuring to the development of multiplicative thinking. (ASK)

Some activities are provided to help students develop a conceptual understanding of perimeter, area, and volume, as well as developing skills in spatial visualization and formulating generalizations. (MNS)

The evidence suggests that students in grades 5 through 8 have difficulty relating isometric type drawings to the rectangular solids they represent. Errors made by students were analyzed and the effect of instruction in spatial visualization activities assessed. (MNS)

The relationship between eight skills and one concept used on maps and their companion spatial abilities in mathematics are presented and discussed: symbols, perspective, location, direction, distance, relief, elevation, scale, and territoriality. (MNS)

The properties of the cube are explored. A set of activities is given that forms the basis of a class project on discovery. (MNS)

Geometry is viewed as the most neglected area of the elementary school mathematics curriculum. Tangram activities provide numerous worthwhile mathematical experiences for children. A method of constructing tangrams through paper folding is followed by suggested spatial visualization, measurement, and additional activities. (MP)

Geometry tiles can be used to develop and extend intuitive geometric concepts by helping children visualize geometric shapes and communicate spatial relationships. Eleven activities are described for introduction, basic concepts, geometric figures, transformations, and metric geometry. (MNS)

Presents interesting activities to develop mental imagery and the ability to transform these images. Concludes that using images facilitates mathematical thought in numerical and geometric settings. (ASK)

The aim of this study was to gain a better understanding of the difficulties met by adults with lower levels of education on reading perspective drawings. Subjects were asked to describe verbally two perspective drawings of objects, then choose objects with defined spatial properties. Results indicated that success was an "all or…
