Vicki Davis’s blog Cool Cat Teacher, gives many ideas for the classroom. She offered a wide variety of resources as well as lesson plan ideas to aid teachers. One of the links she posted was for a website that offered free textbook-like pages to help give students guidance.
The site, CK-12, allows students to pick a subject they are working on, and receive more information on that subject. This could be beneficial for multiple reasons; if the textbook that is available needs supplemental work, this would be an excellent resource or if a student is struggling with the concept, this could provide some extra guidance. It could be an excellent resource for teachers.
