India's trusted abacus and mental skills franchise network — empowering 1000+ children with lifelong cognitive skills through Abacus, Vedic Maths, Olympiads, and more across 50+ centres.
The abacus is one of the world's oldest calculating tools — but its real power lies in what it does to the developing brain, not just numbers.
Abacus training activates both hemispheres of the brain simultaneously. The physical movement of beads engages motor skills while mental visualisation builds the brain's spatial and numerical processing centres — creating permanent cognitive improvements.
OBN is not just abacus — we offer a full suite of mental skill programmes for children aged 5–15.
The flagship programme. Children learn to calculate using the abacus and progress to doing complex arithmetic entirely in their mind — at lightning speed.
Based on ancient Indian sutras, Vedic Maths teaches students shortcut techniques to solve complex calculations mentally — perfect for competitive exams.
OBN organises its own State & National Level Olympiads in Abacus, Science, Mathematics, and Drawing. We also prepare children for external competitions — school to national stage.
