This site is a great way for anyone to expand their vocab. It allows teachers and students to create lists and has thousands of already made lists from literature, speeches, history, current news, plus more.
Great resource for CCSS-ELA. This site is geared for grades 5-12. The library is full of informational and literature text that can be found by lexile range, grade level, theme, genres, device or standards. You have the ability to get paired text, related media (videos), a teacher guide, and a parent guide. Assessment and discussion questions are included that asked students to prove their answers using passages from the text.
While you need a membership to join this site and access all of the resources, there are great real world examples of math that correlate to many different concepts taught in middle school and high school.
An educator I have followed for many years gives some insights into how GAFE (Google Apps for Education) works and how it compares to free-range / "vanilla" Google tools.
