The non-profit CK-12 Foundation offers free STEM activities through digital textbooks in science, technology, engineering, and mathematics subjects (STEM!). CK-12 aligns with state standards. These digital textbooks are available for download on your computer, iPad, Kindle, or other compatible e-reader.
They also offer interactive learning – for example, you may create your own classroom or group, and assign your students lessons in math and science subjects.
Here’s a video explaining the CK-12 Study Guides better than I can:

All of the CK-12 are Kindle- or eReader- ready and available for immediate download at the Kindle store, here. Most of them are free!

These look fantastic! However, although it is labeled CK-12 (which I took to mean it goes from K – 12) I don’t see any books for grades 5 and below. I’ll be doing 6th next year, though, and I saw 2 or 3 that I’m very interested in….
Thanks for this find!
WOW! Just last night my son (8th grade) was saying that he wanted to take Physics. I was like…. duh…. how am I going to find books and teaching videos for that? …and along came THIS post on your site!
I can not thank you enough!
Thank you, I’ll certainly be checking it out!
I love finding freebies for my high schooler. The topics were well covered and pretty straight forward.

Thank you! That makes us feel very proud of what we do. Please share the word around.

Loved the books. My kids are a little young, though. I wish they would come out with introductory level on these topics. My kids are all highly gifted and well beyond their grade level in math and science, but still early elementary. Maybe they will expand.
Thanks so much! I had stumbled on the free downloads from Amazon, but knew nothing about them. Looking forward to exploring what might work for my kiddos!
This is a totally awesome website! I love the freebies and the creativity of the vision here.
