HeyMath! was founded in May 2000 by Nirmala Sankaran and Harsh Rajan on a worldview that there is no perfect education system. We're based in Chennai, India, and are privately funded. Contact our founders.
We've made it our mission to create a flat world video curriculum by diligently seeking out proven best practices from great teachers and discerning parents around the world. Our highly capable Math editors then blend this collective wisdom into bite-sized animated and interactive explanations that provide concept clarification visually and help remove the fear of Math. HeyMath! lessons are developed with advice from the University of Cambridge and endorsed by the Singapore Teachers' Union.
The resources contained in this collection offer a sample of the various lessons available through the HeyMath! program.
