The use of microcomputers to aid geometry instruction is emphasized through discussion of a program written in BASIC which provides for experimenting with polynomial curves. The program listing is included. (MP)

Described are four hour-long sessions of children working with the definition and use of a procedure for triangles in Logo programming. The conclusion is that turtle geometry is not a trivial activity. (MNS)

This document primarily consists of source code listings for software developed under a grant from the National Science Foundation and the National Institute of Education (NSF/NIE). The code contains the following learning games: (1) Turn and Match; (2) Logic Arcade; and (3) Logic Gates. Also included are an assembler for the 6502 microprocessor…

The project described in this article grew from the observation that many geometry students are unable to see anything in a diagram beyond a static presentation. A computerized microworld called "Motions" is described, with illustrations. (MNS)

Some examples are given of geometric exploration and problem solving in which Logo is the primary tool and turtle graphics is the mathematical environment. Students can explore and develop important patterns while building visual intuition. (MNS)

Activities focus on the use of computers as an instructional tool. Three worksheets provide experiences with: perimeter and areas of squares; area of parallelograms and triangles; and properties of triangles. A Logo computer program is included. (MNS)

Shortcomings of current curricula for geometry in the elementary school are discussed. The use of the computer programing language Logo to develop geometric ideas is described, with supporting research. (MNS)
