A timed sheet on 10s

The 10 times table, 10 × 0 through 10 × 12. 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 10s goes wrong

The 10s are notation rather than multiplication — append a zero. The risk is a child extending that rule to the 11s and 12s, which is why a 10s sheet is nearly useless as a speed measure and useful instead as the place where a rule and a fact get told apart. Full marks here is the default, not an achievement.

Three that come up

Is multiplying by 10 a math fact?
It is a place-value rule rather than a fact to memorize: write the other number and append a zero.
Why give a timed test on the 10s at all?
To confirm the rule is automatic, and to catch a child who has generalized it to 11 × 7 or 12 × 7.
What score is expected on a 10s sheet?
Full marks. Anything less points at reading the sheet, not at the table.
