Delivering a math lecture is a circus-worthy feat: juggle the unique confusions of every student, balance perfectly on the tightrope between too easy and too hard, keep a tough crowd constantly intrigued, and do it all in precious little time.

We allow each student to work at their own pace and automate checks for understanding. When students get stuck, teachers can perform interventions with surgical precision, skyrocketing teachers' efficiency at doing what they do best.

Why are students missing basic skills from two grades ago? Why can't they reproduce on the test the material covered two weeks ago?

When learners invent math for themselves, they never forget it, and can even rederive their knowledge. Students achieve mastery the first time, and carry durable foundations into the future.

Students walk into math class uninterested, and walk out trying to memorize big ideas like lines from a play. They don't think math is "for them."

Let them write the script and take on the challenge of solving novel problems. As they work through content at their level, they'll start asking their own questions as they quest to become ever-sharper mathematicians.
