OER (Open Educational Resources) Commons is a site through which educators share lessons and resources. The site hosts thousands of lessons which can be searched by content, lesson type and level. The lessons are licensed to be used and reused free of charge. All lessons have been reviewed and approved by the OER Commons staff. One thing that would make this website better would be to organized the lessons by actual grade level, rather than by just “Primary, Secondary and Post-Secondary”. Maybe that will be added in the future.
