The URL of the page you speak of, now forwards to the Thinkfinity Resources page where we feature the various Content Partner websites, the groups our Content Partners maintain within the Thinkfinity Community and a resource of their choice, which may change from time to time.
Watch for a feature including 21st Century Skills, but in the meantime, please use our two search options to look for resources that fit your students' needs.
If you use the Keyword/Standards Search you can search for 21st Century Skills resources using the Common Core Standards for your state.
Another option is the Search Community search located in the upper right of your screen. A search for "21st Century Skills" there will give you a list of community resources and member-recommended web resources tagged as such.
If you need help finding resources, please start a discussion in the Community Hub. Our members are always eager to help.
