Learn Zillion is an excellent site for getting free video lessons set to state standards. This site is ideal for educators, parents, and students for grades 9 and up. Right now the only video lessons I can find are on all aspects of math/algebra/geometry etc. but I'm assuming other subjects are soon to come.
I highly recommend checking out Learn Zillion by clicking here!!
