Examples of CLOPAK Networks, an approach to covering the plane with symmetrically arranged, close-packed geometric shapes, are given. Implications for the place of networks in geometry instruction are discussed. (MN)

Accuracy of memory for left-right orientation of single forms varying in meaningfulness and complexity was studied in 120 subjects at 5 age levels from kindergarten to adulthood. Complexity was found to be unimportant, but orientation of meaningful figures was remembered better than orientation of non-meaningful figures at all ages. (GO)

Transformations are defined and described through many examples. Teaching aids and activities for teaching about transformations are suggested. (JT)

Provided are student activities to introduce the geometric concepts of line symmetry and rotational symmetry as related to Hawaiian quilting patterns. Paper squares, scissors, and folding techniques afford the teacher the chance to stimulate class discussion about pattern recognition and to integrate mathematics with the cultural world outside the…

Described is how folk art can be used to teach spatial thinking and symmetry. Activities are open-ended and can be used for all age groups and levels of development. Mathematics is integrated with the study of culture, art, and history in these activities. (KR)
