The Digital Education Network offers 7th through 12th grade students a chance to expand their knowledge in four areas: NewsDEN, which covers current events for kids and provides tips for teachers on how to integrate the information into their curricula; MathDEN, an interactive math challenge that offers four "stages" for students at different levels and tracks their progress (new question sets are added every Thursday); InternetDEN, a tutorial on using Internet tools for education, aimed at the novice net-surfer; and GraphicsDEN, a tutorial on and gallery of computer graphics. Planned for release next month are WritingDEN and SkyDEN, two new instructional areas. Free registration is requested before using the site, but a "guest" login is also available.
