Sample Lessons

There's no better way to get a feel for what the K¹² experience is like than to take a look at some sample lessons.

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.

K–8 Lessons

Check out some lessons from all six of our core K-8 subjects, from Math to Music, organized by grade level.

High School Lessons

Take a look at some of our newest lessons for the upper grades. These highly interactive, robust lessons give older kids the chance to work more independently.

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.
