The National Science Digital Library

The National Science Digital Library

 The National Science Digital Library is the nation’s online library for education and research in science, technology, engineering, and mathematics. It provides free math lessons and activities aligned with the Math Common Core Standards, as well as STEM-related blogs and other free teacher resources and lesson plan ideas. Targeted for K-12 teachers, higher-education professionals, and librarians, NSDL also provides science literary maps and iTunes multimedia files.  Althrough this is not a tool, this site does have great material in it for teachers to use and thus I've added it to my website.
