A concrete and a symbolic approach to learning multiplication in the second grade are studied. The results, indicating that children using the symbolic model performed at a higher level than those using a concrete model, are discussed. (DT)

A method of showing the meaning of decimal fraction without using fraction words or notation. One technique described in detail uses large squares, strips, and small squares; using the metric system and decimal coinage is also suggested. (DT)

Examples are given of activities that begin with the classification of objects into sets and lead to concepts and activities in other branches of mathematics, in language arts, and in science. (DT)

Reviewed are the Avon materials and a set of kits for teaching the metric system. (MM)

Described are uses of ceramics in educational programs of broad application to handicapped, particularly, mentally retarded, children. Benefits in social, emotional, and mental growth are identified. (Author/KW)

Discussed are new media being used in classroom mathematics instruction; television, computers, programed materials, films, games, manipulative materials. (CT)

Index cards, masking tape, pizza shells, golf tees, and empty soda bottles can be used to make manipulative objects to be used in children's mathematics games. Twenty-two games that provide practice in number drills and problem solving are described, along with instructions for making objects needed for the games. (PP)

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)

Ways in which bead strings can be used for reinforcement and concept development are noted. After discussion on how to make bead strings, the material looks at: (1) prenumber concepts; (2) more than, less than; (3) conservation of number and numerals and numerousness; (4) addition and subtraction; and (5) place value.

The use of money to teach mathematical topics such as fractions, percents, decimals, and nondecimal numeration is encouraged. (MP)
