The value and technique of pre-geometry and geometry instruction in the primary grades are discussed. Geometric concepts such as open and closed figures, connectedness, similarity, congruence, straightness, and angle are presented through suggested activities, lesson plans, and evaluation procedures. (SD)

A unit on the peoperties of a kite can include many geometric concepts: symmetry, distance, relationships between diagonals, area, altitude, angles, and others. (SD)

The Czechoslovakian Academy of Sciences is sponsoring an experimental approach to the modernization of the geometry curriculum. Geometry is viewed as ancillary to other parts of the curriculum and is taught as appropriate to other subjects (e.g., algebra). Combinatorial geometry is taught formally. (SD)

From a special report, "What's New in Curriculum

AN INVESTIGATION WAS MADE TO DETERMINE WHETHER AN OVERHEAD PROJECTOR AND TRANSPARENCY SET WOULD BE MORE EFFECTIVE AND ACCEPTABLE TO TEACHERS AND STUDENTS THAN TIME-PROVEN CHALKBOARD DRAWINGS IN THE TEACHING OF A DESCRIPTIVE GEOMETRY COURSE. IT WAS FOUND THAT (1) THE LECTURE-DEMONSTRATION PERIOD CAN BE REDUCED TO ALLOW A LONGER SUPERVISED…

This paper reports two experiments related to elementary school children's learning of geometric concepts. The geometry experiment investigated the effects of location of practice problems within a programmed text; the polygon experiment involved two variables, number of illustrative examples presented, and number of practice problems given. Both…

This is one in a series of SMSG supplementary and enrichment pamphlets for high school students. This series is designed to make material for the study of topics of special interest to students readily accessible in classroom quantity. Topics covered include directed segments, applications, components, and inner products. (MP)

This is one in a series of manuals for teachers using SMSG high school supplementary materials. The pamphlet includes commentaries on the sections of the student's booklet, answers to the exercises, and sample test questions. Topics covered include directed line segments, applications to geometry, vectors and scalars, components, inner product,…

This volume contains preliminary versions of five of the chapters prepared by the SMSG curriculum project for use in grades 7 and 8. The first four chapters and the tenth chapter in the sequence are presented. The sample chapters in this volume illustrate a number of aspects of the curriculum project: (1) association of ideas of number and space…
