OpenEd is a repository of online educational materials that are aligned to the Common Core standards. It contains a searchable database of videos, games, courses and assessments. The resources can be browsed by topic, grade level and standard. In addition to the resources, OpenEd has a practice assessment generator which allows teachers to add multimedia to the questions. (A free login is required to use the assessment tool.) While OpenEd’s mission is to supply resources for supporting the flipped classroom model, the resources on this site can be used to support learning in any classroom.
