Technology Problems of the Week (tPoWs) are freely accessible problem-solving challenges modeled on our Problems of the Week that take advantage of interactive mathematics tools such as Java applets, TI-Nspire™, The Geometer's Sketchpad®, Fathom™, or spreadsheets. Students are invited to use the link "Submit your answer" to share their solutions, and then "self-mentor" using specially designed hints, checks, and suggestions for extensions.
dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. It offers multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked.
While other interactive software (e.g. Cabri Geometry, Geometer's Sketchpad) focus on dynamic manipulations of geometrical objects, the idea behind GeoGebra is to connect geometric, algebraic, and numeric representations in an interactive way. You can do constructions with points, vectors, lines, conic sections as well as functions and change them dynamically afterwards. Furthermore, GeoGebra allows you to directly enter and manipulate equations and coordinates. Thus you can easily plot functions, work with sliders to investigate parameters, find symbolic derivatives, and use powerful commands like Root or Sequence.

communicate something online by recording a sketch, optionally with your voice speaking. Any sketch can then be embedded on your blog/ homepage for people to play-back, and you can also point people to your sketchcast channel here (or let them subscribe to your sketchcast RSS feed). Create a tutorial explaining how boomerangs work (and why they don't always return). Draw a doodle of your ex. Explain a math formula. Create a cartoon (you can use the eraser tool to make place for several panels of the cartoon). Get a partner and explain a concept together... voice recording doesn't have to be used by only one person! Write a love letter with lots of sketching inbetween. Create an online Chinese course and explain Pinyin writing. Create a masterpiece and show others how to draw. Explain baseball to Europeans... or explain soccer to Americans! Create a riddle for kids: draw something and the kid has to guess while you're drawing. Draw a manga action scene. Or many other drawing ideas.
