Bead Basics
Learn to read and set numbers on the abacus. Understand earth beads (1s) and the heaven bead (5). Master numbers 0-99.
Simple Addition
Add single-digit numbers without carrying. Learn to use the heaven bead for adding 5. Master basic addition techniques.
Simple Subtraction
Subtract without borrowing. Remove earth beads and heaven beads. Handle two-digit subtraction.
5-Complement (Friends of 5)
The first key technique! Learn to add and subtract using the 5-complement when earth beads are full or empty.
10-Complement (Friends of 10)
The second key technique! Carry over to the next rod when adding past 9. Borrow when subtracting below 0.
Multi-Digit Calculations
Apply all techniques to 2-digit and 3-digit addition and subtraction. Chain multiple operations together.
Speed Training
Timed exercises to build speed and fluency. Quick-fire single and double-digit problems. Introduction to Flash Anzan.
Mental Abacus
The ultimate skill — calculate without looking at the abacus. Visualize bead movements in your mind. You are now a mental math master.
The 3 Stages of Mind Transformation: From Wood to Thought
How does a child go from physically sliding wooden beads to calculating 5-digit sums in their head in 1.5 seconds? Here is the cognitive roadmap behind our 8 levels.
Stage 1: Tactile Conditioning
The fingers must physically touch wooden beads. Feeling the weight of the beads and hearing the crisp click against the reckoning bar creates a multi-sensory sensory imprint. Without physical tactile familiarity, the brain cannot construct a stable mental model later.
Stage 2: The "Air Soroban"
The student looks at an empty desk or worksheet while their right thumb and index finger twitch in mid-air. They no longer need physical wood, but still rely on motor-cortex muscle memory to maintain spatial orientation of columns and carry-overs.
Stage 3: Photographic Anzan
Physical motion stops entirely. The mental abacus appears as a high-definition, vivid image on the brain's internal screen (visuospatial sketchpad). Numbers update instantly in silence at speeds exceeding human verbal speech.
An Honest Classroom Note for Parents and Tutors
When students transition from Level 3 to Level 4 (The 5-Complement) and Level 5 (The 10-Complement), calculation speed temporarily drops by almost 50%. This is not failure—it is the brain rewiring from simple direct counting to algebraic formula substitution. If your child feels frustrated here, do not push them forward. Spend an extra week drilling on Complement Drills. Once this bridge is crossed, their speed will accelerate permanently.
