"OpenEd, the leading K-12 educational resource library, offers over a million assessments, homework assignments, videos, games, and lesson plans aligned to standards including Next Generation Science, Common Core Math and English Language Arts, TEKS, and many more. We think teachers should be able to find any online resource they need, all in one place, and all organized by what is most effective for students. We also think assessments and homework should be graded automatically to save teachers time. Plus, we sprinkle some OpenEd magic on our resources- for every question a student misses, OpenEd returns a hand-picked, targeted video or game to help the student master that specific concept. That's instant, personalized remediation to help save teachers time!"
