Designed for educators, the Interactivate website provides numerous high quality resources that assist with the “creation, collection, evaluation, and dissemination of interactive courseware for exploration in science and mathematics.” The What's New area provides interested parties with new and updated activities that are quite compelling. One of the more recent additions is Function Revolution, an activity that allows users to find out about the volume and surface areas of various functions as they are rotated around axes. Moving on, the For Teachers area showcases over a dozen recently updated lessons, including activities on Algorithm Discovery with Venn Diagrams and Conic Flyer Equations.
