The popular and free digital tool, ThingLink, is an astonishingly easy way to create interactive graphics that encourage collaboration, increase engagement, and enliven lessons and homework. After signing up for a Basic Education account (other options are available, some at cost), users are led through several steps to create interactive, annotated images. For instance, an uploaded image of a historical figure, such as Harriet Tubman, may be "tagged" to link to an informative website, video clip, or other rich media from around the web. Users may also annotate directly onto the image themselves. Various tutorials dedicated to such topics as Image Tagging, Adding Content, Creating a Class Group, Creating a Channel, and other topics, make for an easy process. ThinkLink is available for Desktop, iOS, and Android devices.
