The author strongly questions the arbitrary and random usage of diverse experiences, labs, games and activities in the mathematics classroom. He urges that teachers not substitute these activities for carefully planned, sequential mathematics instruction. (CT)

Using plastic letters and capitalizing on tactile cues can help reading disabled students sort out perceptual confusions. Three case studies depict the tactile approach's value in teaching reading and spelling as well as in promoting generalization. (CL)

Introduces concepts of modern algebraic group theory in the form of a game. Peg boards and rubber bands represent nonnumerical group elements and are manipulated under the operation of reorienting a regular polygon. Symmetry groups are used to explore set properties, as well as commutative and noncommutative operations. (CMS)

This article shares activities that fourth, fifth, and sixth graders can enjoy as they discover relationships among fractions, decimals, and percents, including the 100-penny chart. (MKR)

Technology education at the elementary level involves hands-on, appropriate activities to introduce children to tools and to enhance their personal growth, creativity, and understanding of the world. Manipulation of materials can make abstract mathematical concepts concrete. (SK)

Three groups of 12-month-old infants were tested for cross-modal and intramodal transfer of information about shape. Infants were given either visual or tactual familiarization and then tested for visual or tactual recognition. Overall, intramodal transfer was superior to cross-modal transfer. Cross-modal asymmetries were found for which possible…

Suggests using manipulatives with young children to create imaginary solutions to fantasy situations. Includes activities that use the problem-solving format: stating the problem, brainstorming solutions, experimenting, carrying out the solutions, and evaluating the solutions. (JOW)

Presents an activity for weaving polyhedron shapes out of paper strips. (MVL)

Mathematical meanings can be developed when individuals construct translations between algebra symbol systems and physical systems that represent one another. Previous research studies indicated (1) few high school students connect whole number manipulations to algebraic manipulations and (2) students who encounter algebraic ideas through…

The use of these sticks is suggested as an enrichment activity. The method of construction is described. (MP)

Three studies of stereotyped object behaviors conducted with 10 severely mentally retarded children (6 to 19 years old) found that context did not affect the level of object stereotypes, that most children responded to flexibility, and that judges could estimate only some of the feedback properties of the objects.

Extracts from "Experimenting with Numbers" by Margaret Stern demonstrate the use of Stern Blocks to develop the conceptual base on which learning disabled students can build further mathematical skills. (DB)
