is an online community for K-12 teachers to develop science, math, and language arts-based curricula, complete with lesson plans, software to download or use online (as well as support to help teachers use that software), and message boards for teachers everywhere to communicate and help one another. The online resources build on Riverdeep Interactive Learning’s courseware and interactive simulations. The site offers access to Riverdeep’s EarthPulse research center as well, which is ideal for helping students understand the impact of geological and atmospheric events on our changing earth. Though much of the site’s content is available only on a per-fee basis, Riverdeep offers educators a free 90-day evaluation period.
