A timed sheet on 8s

The 8 times table, 8 × 0 through 8 × 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.

Where 8s goes wrong

The 8s are doubling three times: 7 × 8 runs 7 → 14 → 28 → 56. Three steps means a single slip moves the answer a long way, so 8s errors tend not to be near misses — they come back at double or half the correct value. Checking whether the answer is exactly twice the matching 4s answer catches almost all of them.

Three that come up

How do you multiply by 8 quickly?
Double three times. 6 × 8 goes 6 → 12 → 24 → 48.
Why are 8s mistakes usually far off?
Because the shortcut has three steps. Dropping one step halves the answer, adding one doubles it.
Is the 8 times table related to the 4s?
Every 8s answer is exactly double the matching 4s answer, which makes the 4s sheet a useful check.
