A timed sheet on 4s

The 4 times table, 4 × 0 through 4 × 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 4s goes wrong

The 4s are doubling twice: 7 × 4 runs 7 → 14 → 28. That dependency is strict, so a wobbly 2s table guarantees a wobbly 4s table. Every answer is a multiple of 4, which gives a second check — halve the answer and if the half comes out odd, the answer was not a multiple of 4 to begin with.

Three that come up

What is the fastest way to multiply by 4?
Double, then double again. 6 × 4 becomes 12, then 24.
Can I check a 4s answer?
Halve it twice. If either halving leaves an odd number, the answer is not a multiple of 4.
Should the 4s come before the 3s?
Either order works. The 4s lean on doubling, which most children already have; the 3s introduce a new rhythm.
