FREE—the Federal Registry for Excellence in Education—offers access to more than 180,000 digital resources organized both by education topic (language arts, math, science, art and music, health, and history) and by standards in math, science, and geography.
FREE’s thousands of offerings include The Science of Music, on why some songs stick in your mind and other music-based science (created by the San Francisco Exploratorium), MegaMath, which introduces math concepts to elementary school children, (the Los Alamos National Laboratory), and All About Snow, with extensive materials ranging from how a snow flake forms to avalanches (the National Snow and Ice Data Center).
FREE is one of the most popular K – 12 websites operated by the U.S. Department of Education. Begun in 1997 by presidential request and upgraded in 2006, it draws from more than 65 Federal agencies. FREE posts updates and its Twitter feed @FreeResources links to resources connected to historical events by the current day (an “on this day” feature). RSS feeds are also available.
