Click beads toward the bar to count them. A soroban-style abacus for practicing place value.
About this tool
This follows the soroban layout: each column (rod) represents one decimal place. The single bead above the bar is worth five when moved down to it; the four beads below are worth one each when moved up to it. Click any bead to slide it toward or away from the bar.
Try it
Move one lower bead on the rightmost rod to the bar for 1, then the heaven bead on the same rod for +5 — you've made 6.
