Spotlight on West Virginia’s Teach 21 website

West Virginia’s Teach 21 website contains educator-developed resources aligned to the Common Core State Standards, which the state calls Content Standards and Objectives (CSOs), and the state’s other standards. The website contains interactive digital resources, including interactive CSOs, Next Generations CSOs for ELA and mathematics, strategy bank, and instructional guides aligned to the Common Core. Since the state implemented the kindergarten standards in the 2011-2012 school year, the Teach 21 website includes many rich lessons and resources developed by teachers on the kindergarten ELA and math standards.
