Whether you
pick and choose from its 22 major topics or use the whole curriculum, CK-12 has
enough lessons to keep any class working hard and learning. It’s heavy in lessons
for math and the sciences with everything from geometry, calculus and the
secrets of mental math to how photosynthesis works, but there are also sections
for U.S. history and economics. Many of the lessons have discussion topics and
assessments built in. All are available online, but some have .pdfs and ebook
files available as well as interactive material and videos.
