A timed sheet on 0–12

All addition facts from 0 + 0 to 12 + 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

What the 0–12 addition set contains, one row per fact family.

Where the full addition set goes wrong

Addition 0–12 is 169 cells, but commutativity means half are facts already known from the other side — a child with 9 + 4 does not need 4 + 9 as a new fact. What actually separates children in this range is sums over ten, which is exactly where fingers reappear. Below ten this sheet measures speed; above ten it measures strategy.

Three that come up

How many addition facts are there from 0 to 12?
169 pairs, or 91 once you count 4 + 9 and 9 + 4 as one fact.
Where do children slow down on an addition sheet?
On sums crossing ten. Below ten the answer is usually recalled; above ten it is often counted.
Does order matter in addition practice?
Not for the answer, but seeing both orders on a sheet is useful — it shows whether the child knows they are the same fact.
