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.
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.
