"Recently, MasteryConnect unveiled a cool, social bookmarking feature for standards aligned resources. Much like the Pinterest paradigm of social bookmarking, teachers find or upload any resource on the web, align it to a state or Common Core standard, and “pin” it to a board or collection. Like MasteryConnect’s community of teacher-created formative assessments, it seems that MasteryConnect is at it again, working to create the biggest collection of resources for the Common Core."
