Precalculus Page | Interactive On-line Geometry |
Federal Resources (FREE) THE PRECALCULUS PAGE Lesson plans and staff development activities with a problem-solving approach. Materials focus on logarithms, the binomial theorem, and the law of sines: Problems (without answers) on algebra, exponential and logarithmic functions, other functions, geometry, and sums, sequences, and series are available: The site also offers pages of useful links for teachers, and lesson plans with activity overviews from 1998 summer workshops at Portland and Eugene, Oregon: -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- GALLERY OF INTERACTIVE ON-LINE GEOMETRY The Geometry Center Twelve interactive online geometry programs: - WebPisces: compute implicitly defined curves in the plane - Build a Rainbow: examine a mathematical model of light passing through a water droplet - QuasiTiler: generate Penrose tilings or design your own nonperiodic tilings of the plane - Kali and Kali-Jot: use an interactive editor to learn about symmetric patterns of the plane - Cyberview-X: define your own 3D objects with this interactive 3D viewer - Projective Conics: Pascal's theorem in terms of projective geometry: specify points on a conic and see how the theorem applies to them - Orbifold Pinball: explore the effects of negatively curved space - Teichmuller Navigator: explore the space of all different angle geometries on a genus two surface - Integrator: experiment with numerical integration of data sets - Unifweb: discover and visualize families of Riemann surfaces - Lafite: work with any discrete symmetry group of the hyperbolic plane -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- FEDERAL RESOURCES FOR EDUCATIONAL EXCELLENCE (FREE) A collection of educational resources from the Department of Education, Department of Energy, and other federally supported organizations. Subject listings include mathematics: The site also offers a search engine, favorite sites (reviewed by users), more sites for students, comment and feedback forms, and an invitation to be a FREE partner in developing Internet-based learning modules and communities: -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- JUST FOR FUN: VOTE! To show students the impact of using the Internet to collect data, even if only a simple opinion, John Euchler asks you to visit a page from his 7th grade class at Saint Stanislaus Kostka School and vote on your favorite mnemonic device for remembering the digits in the number pi: -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- 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\ / \ / \ / | / \ / \
