Connecting Geometry - Sanders | Native American Geometry |
Math Magic - Friedman CONNECTING GEOMETRY - Cathleen V. Sanders An interactive electronic geometry course offered via the Internet to students throughout the Hawaiian islands. During the course Cathi Sanders, a teacher at Punahou School in Honolulu, communicates with students through a Web page and via e-mail. The course uses computer technology and the Internet to explore and discover the principles and concepts of geometry. Students explore geometric figures using the Geometer's Sketchpad, practice geometric skills through problem-solving activities on paper, explore applications of geometry through the Web, and create projects using these technologies. Chapters include: - Communicating in Geometry - Symmetry and Transformations - Theorems in Geometry - Congruent Triangles - Triangle Properties - Right Triangles - Parallel Lines and Planes - Polygons - Similar Triangles - Circles - Perimeter and Area - Surface Areas and Volumes -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- NATIVE AMERICAN GEOMETRY - Chris Hardaker Native American geometry is a physical, proportional geometry that originates from the circle. A growing body of architectural and iconographic evidence suggests that this geometry was a relatively common tradition and has been practiced for at least 2000 years. The site is divided into four areas: Foundations, Anthropology, Designs, and Education; it introduces this two-dimensional non-random geometry in a connect-the-point format, exploring the intellectual and cultural implications of pre-Columbian geometric traditions in the New World. It also provides a list of European mathematical ramifications of the designs. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- MATH MAGIC - Erich Friedman A site devoted to original mathematical recreations. Send your math puzzle, discovery, or observation, to the author, or submit an answer to the problem of the month. Past questions and solutions are archived. Examples include: - Divisor Chains - Integer Square Tilings - Angle Frequencies - Disconnected Polyominoes - Average Arrays - Convex Spectra - Surround Numbers - Palindrome Products -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum Ask Dr. Math Problems of the Week Mathematics Library Teacher2Teacher Discussion Groups Join the Math Forum Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \
