Creswell, John L.; Wiscamb, Margaret – School Science and Mathematics, 1970

Presents techniques and materials for instruction at secondary school and upper elementary grades in mathematical concepts of number systems structure. Grouping is used as a simple algebraic system to illustrate structure. Closure, inverse, identity, commutative and associative properties are examines relative to manipulation of geometric figureS.…

Balka, Don S. – School Science and Mathematics, 1975

Many fundamental geometric figures can not be constructed on the familiar square geoboard (e.g., equilateral triangle, regular hexagon). Activities which can be used with an isometric geoboard for study of these figures are catalogued. (SD)

Trent, John H.; And Others – School Science and Mathematics, 1972

The results of a study of UICSM materials for seventh and eighth grade low achievers show that students studying Stretchers and Shrinkers learned just as much arithmetic as students in traditional programs and that students studying Motion Geometry did significantly better in arithmetic application and total score on the Stanford Achievement Test…

Pullman, Howard W. – School Science and Mathematics, 1979

Pick's Theorem, a statement of the relationship between the area of a polygonal region on a lattice and its interior and boundary lattice points, is familiar to those whose students have participated in activities and discovery lessons using the geoboard. The proof presented, although rather long, is well within the grasp of the average geometry…
