I must forewarn all non US teachers that FREE is very focussed on catering to the US curriculum but none the less it is definitely full of relevant content to international teachers. FREE makes it easier to find teaching and learning resources from a number of federal government departments.
More than 1,500 federally supported teaching and learning resources are included from dozens of federal agencies. New sites are added regularly.
FREE was conceived in 1997 by a federal working group in response to a memo from the President. The site was launched a year later. It was redesigned and relaunched for the first time in November 2006.
FREE is among the most popular K-12 websites maintained by the U.S. Department of Education because of the many great resources being offered by contributing federal agencies.
FREE is very easy to naviagate and contains a wealth of great resources. Check it out here.
