It's comprised of interactive explanation sections, where you can learn all units enjoyably with full animation and full voice, and problem-solving practice sections to solidify academic skills.

We meticulously focused on native expressions and native voices to ensure children can learn math naturally in either language. Even the humor is designed in consultation with native speakers.
