- Parts of the Soroban
Learn the physical structure of the soroban before solving with it.
- Reading a Single Digit
Read one soroban rod accurately before moving to larger numbers.
- Place Value on Two Rods
Move from single digits to two-digit numbers by respecting rod position.
- Reading Two-Rod Numbers
Learn to read two-rod values as structured place value before arithmetic begins.
- Setting Your First Numbers
Practice placing simple values cleanly and intentionally.
- First Addition on One Rod
Begin addition with controlled changes on a single rod.
- First Subtraction on One Rod
Learn subtraction as careful removal, not rushed guessing.
- One-Rod Number Pairs
Train easy one-rod pairs so direct movement feels clean before complements become necessary.
- Complements to Five
Use number pairs to move more efficiently on the soroban.
- Complements to Ten
Learn the pairs that complete ten so larger transitions feel cleaner.
- Complement Ladders
Use complement ladders to make five- and ten-partner recall faster and smoother.
- Mixed Two-Digit Fluency
Build calm fluency with two-digit mixed operations before speed becomes the goal.
- First Multiplication Patterns
Start multiplication through repeatable groups, clear roles, and bead movement you can actually follow.
- First Division Patterns
Begin division through equal groups and missing-factor thinking before more formal quotient building.
- Place Shifts in Multiplication
Learn how multiplication changes place, so problems like 12 × 3 feel structured instead of chaotic.
- Building Quotients in Division
Extend exact division into stronger quotient-finding habits so the operation feels deliberate instead of lucky.
- Mental Soroban Sequences
Start mental soroban with short, readable sequences that train stable internal totals before speed becomes the goal.
- Speed Rhythm and Error Checking
Learn how to increase speed while keeping the total stable, the rhythm controlled, and errors small enough to catch quickly.
