A timed sheet on dividing by 10

Dividing by 10, from 0 ÷ 10 to 120 ÷ 10. Every problem on the sheet is drawn from that set and nothing outside it.

Choose 20, 50 or 100 problems and a limit of 1, 2 or 5 minutes, then print the sheet with its answer key on page two, or start the timer and type into the same grid. The problems are drawn again every time the page loads, so a second sheet is not a copy of the first. How the counts and limits work is on its own page, along with what a timed test does and does not measure.

Thirteen rows, with the answers

Where dividing by 10 goes wrong

Dividing by 10 is removing a zero, and since nothing here leaves a remainder every dividend ends in one. The only real hazard is a child carrying that rule forward into dividing by 11 or 12, so this sheet is a place to confirm where a rule stops rather than a place to measure speed.

Three that come up

Is dividing by 10 just removing a zero?
In this set, yes — every dividend ends in 0, so 80 ÷ 10 = 8.
Does the same trick work for 11 or 12?
No. It is a place-value rule tied to base ten and nothing else.
What score is expected here?
Full marks. A miss usually means the sheet was misread.
