Homeschool Resource: CK-12 FlexBooks

 CK-12 FlexBooks

If you are homeschooling a tween or teen, go check this out! While this is geared for traditionally schooled kids, it is a great homeschool resource.  Basically, CK-12 provides organized open source science and math content geared for middle and highschoolers and includes some teachers guides as well. Content is in the form of text for some courses, including review questions and worked problems, and a mix of text, images and video (and other links) for more information and deeper learning in other courses.  Some Khan academy videos are utilized, for example in CK-12 Biology: Cellular Function and Structure.  There is even free SAT prep available from www.Ineedapencil.com.
