This article describes ways in which technology-supported mathematical investigation can engage students with substantive mathematics. It focuses particularly on the ways in which the NCTM Process and Content Standards for the elementary grades can be supported by the use of interactive software such as The Geometer's Sketchpad.

Provides details on how technology can be used to examine the symmetry of human faces and to experience symmetry being created instead of observed. (Author/YDS)

Describes a unit of study focusing on tessellations to show students another view of mathematics. (Author)

The amount and placement of instructional time devoted to various types of computation are crucial. Reviews messages regarding what and how computation should be developed in elementary school mathematics and offers a proposal for a K-8 computation curriculum. (ASK)

States that thinking about numerical procedures starts in the elementary grades and continues in successive grades until students can eventually express and reflect on the procedures using algebraic symbolism. Outlines how such thinking can progress to algebraic reasoning. Illustrates how computers can be used to promote this progression through…

Describes an after-school mathematics enrichment program in which children can freely experiment and play with mathematics and presents research observations. Offers some recommendations to teachers for implementing the program ideas in their classrooms. Contains 18 references. (ASK)

Presents activities that demonstrate how technology can help students discover the mathematics in nature. Claims that these experiences can clarify students' vision of the symmetry of beauty that fills the world beyond the computer. Concludes that the use of flexible software tools helps students explore how a shape is affected when they change…

Uses three computer software programs to help students develop algebraic reasoning. Programs include spreadsheets, Logo programming language, and Teasers by Tobbs. (ASK)
