The Abacus program has been a game-changer for our son. His calculation speed and mental math abilities have improved dramatically. Plus, it really helped with his private school entrance exams. Highly recommend!

Why Choose Us

How Abacus & Mental Math Training Benefits Your Child

At Kiddo Genius in Manhattan, we don't just teach math - we train young minds for life. Our HIKARI® Mental Arithmetic program uses the Japanese Soroban abacus to develop whole-brain thinking through logic, memory, and creativity. Here's what your child gains:

Sharper Focus & Concentration

Abacus training requires intense mental engagement, naturally building a child's ability to concentrate and block out distractions - skills that transfer directly to classroom performance.

Stronger Short & Long-Term Memory

Visualizing and manipulating numbers on a mental abacus exercises both working memory and long-term recall, giving children a meaningful advantage in school and everyday learning.

Analytical & Logical Thinking

By breaking complex calculations into step-by-step mental processes, kids develop structured logical thinking that helps them approach any problem - in math and far beyond.

Faster Mental Math & Problem-Solving

Through consistent brain training, children learn to calculate quickly and accurately in their heads, building the speed and confidence that sets them apart in academic settings.

Visualization & Spatial Awareness

Using a mental abacus activates the right hemisphere of the brain, strengthening spatial awareness and the ability to visualize abstract concepts - a powerful edge in STEM subjects.

Boosted IQ & Emotional Intelligence

Research from the University of Manchester shows Mental Arithmetic practice can increase a child's IQ by up to 7.11 points¹, while also building patience, resilience, and emotional self-regulation.
