Free Common Core Vocabulary Lessons for Grades 9-12

I was doing a little surfing yesterday and came across this site at Visual Thesaurus. These vocabulary lessons are for grades 9-12 and are aligned with the common core. I am creating a vocabulary unit for my freshmen and am definitely using some of these.  If you teach high school and are looking for something a little different and challenging for your kids check it out!
