CK-12 is a free digital learning platform centered on FlexBooks and standards-aligned resources. Teachers can adopt, remix, and assign digital texts, interactives, questions, simulations, and practice while students use them for instruction, reference, or review. A remixed or assigned resource needs its source and version to remain understandable. Teachers connect selected materials with local lessons and any evidence collected from student practice.
