The skill this sheet trains

A soroban holds one digit per rod. Above the reckoning bar sits a single bead worth five. Below it sit four beads worth one each. A bead counts only once it has been pushed toward the bar; a bead resting away from the bar is worth nothing at all. Decoding a rod therefore means asking two questions in order, is the upper bead down, and how many lower beads are up, and answering with one digit. Until that pair of questions collapses into a single glance, a child is looking at a cluttered wooden frame rather than at a number, and no amount of drilling on the formulas above will fix it.

Using the sheet

Print one copy per child. Work left to right along each row, writing the number in the blank beside each diagram. Most beginners take ten to fifteen minutes for all twelve, and the last four, which carry a tens rod, take longer than the first eight on purpose. Finished looks like twelve filled blanks with no crossings-out on the single-digit items. If a child is still counting beads one at a time on item twelve, the sheet has done its job by telling you that, and it is worth printing a second copy for another day rather than pushing on.

What to watch for

The mistake specific to this sheet is counting every bead on the rod instead of only the beads touching the bar. A child who reads a rod showing three as seven has counted the idle beads too. The second most common slip is reading a two-digit diagram right to left, so 38 comes back as 83. Both are reading errors, not arithmetic errors, and both are worth correcting on the spot, out loud, with a finger on the bar itself.

Where it sits in the course

Reading comes before the numbered curriculum begins. It is the readiness check a teacher runs in the first sitting, ahead of Level 1, where direct bead movement starts. See the ten levels in order.

If a child would rather be shown than told, the same two questions are worked through one rod at a time in our free lessons, where you can learn to read the beads step by step before the sheet comes out of the printer.

What to print next

Once reading is quick, reverse it. The same twelve-item format, but the number is given and the beads are blank: Show the Number.
