"Students can access and download tunes from YouTube audio library and use it as a background in their video projects. YouTube has even made it easier for them to search for and find the music they want from its library."
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.
