Our lessons will give you a taste of how the online school works, what kind of planning and progress tools are available, the types of activities—online and off—that are included in the lessons, and a look at just how much thought goes into the production of the curriculum.

Interactive Activities
A hallmark of K¹² lessons is the use of online interactive components within the lesson to engage the student and reinforce the concepts being taught. Sample a few of the many interactive activities that students encounter as they work through K-8 and high school lessons.
