Objectives
- Add small values on one rod.
- Notice when the upper bead helps more than lower beads.
Start with combinations that stay within one rod and can be seen clearly.
Example
If you have 2 and add 3, you now have 5. Instead of thinking only about counting up, notice how the soroban lets you shift into a cleaner bead shape.
Practice habit
After each movement, read the final value before moving again.
