> Digital textbooks and guided support for school learning

CK-12 gives students and teachers digital resources for school subjects, particularly math and science. Its FlexBooks organize lessons into customizable online textbooks, with explanations, diagrams, real-world examples and practice material. Interactive simulations provide another way to explore a concept, while adaptive practice adjusts question difficulty according to the learner's responses.

You can search for a topic, work through its reading and exercises, or ask Flexi, the AI tutor, for a step-by-step explanation and follow-up clarification. Teachers can adapt textbook content to a curriculum and use Flexi to draft classroom activities or assessments, reviewing the generated material before assigning it.
