"Welcome to the Google SketchUp for Educators Community, a site to share, connect & learn This site is brought to you by Google and made especially for Google SketchUp educators and students. Come join and help us build it! Google SketchUp is an easy-to-use program that lets you and your students create, modify and share 3D models. From history to calculus, you'll be surprised at how easy it is to see your ideas in 3D. And when you're done, you can export an image, make a movie or print out a view of what you made."

Maths graphic  calculator

"Free tutorials using java applets to explore, interactively, important topics in precalculus such as quadratic, rational, exponential, logarithmic, trigonometric, polynomial, absolute value functions and their graphs. Equations of lines, circles, ellipses, hyperbolas and parabolas are also explored interactively. Graph shifting, scaling and reflection are also included. The definition and properties of inverse functions are thoroughly investigated. A graphical approach to 2 by 2 systems of equations is included. "

The connection between mathematics and art goes back thousands of years. Mathematics has been used in the design of Gothic cathedrals, Rose windows, oriental rugs, mosaics and tilings. Geometric forms were fundamental to the cubists and many abstract expressionists, and award-winning sculptors have used topology as the basis for their pieces. Dutch artist M.C. Escher represented infinity, Möbius bands, tessellations, deformations, reflections, Platonic solids, spirals, symmetry, and the hyperbolic plane in his works. Mathematicians and artists continue to create stunning works in all media and to explore the visualization of mathematics--origami, computer-generated landscapes, tesselations, fractals, anamorphic art, and more.

"Below is a list of freely available online mathematics, data analysis and graphing resources. * The Interactive Library: Math - This EdInformatics.com site is a list of links to interactive integrated math and science sites. Some Java applets are standalone and some come with lesson plans and notes * The Interactive Library: Calculators - This EdInformatics.com site is a list of links to interactive calculators including a Roman numerals calculator, a graphing applet, a virtual abacus and a scientific conversions applet * Create a Graph - Graph data online * GraphPad - Graph data online The following math and data analysis resources are available for a fee. Commercial products * InspireData - Not an interactive site, but a nice data analysis software tool, by the developers of Inspiration and Kidspiration. You can download a free 30-day trial"

"Secondary Interactive Smartboard Sites "

Simple reflectional symmetry tool which lets children/teachers put colours into four quadrants creating reflecting patterns.

"A centre for teachers, students, researchers, parents, educators, and citizens at all levels who have an interest in mathematics education. Lots of links to resources at other sites."

"Investigates some of the great problems in the history of math and the mathematicians who were inspired by them."

"This is a school's website with excellent examples and solutions on most IGCSE and IB topics. "
