Timed arithmetic practice with the range, operations and length under your control — addition, subtraction, multiplication and division, using whichever numbers from 0 to 12 you tick for the first and the second number. In a subtraction the larger of the two goes first, so the answer is never negative, and in a division the two are multiplied to make the number being divided, so the answer is always a whole number. Each run is scored at the end so progress is visible.
Built for short, repeated practice rather than a course. The problems are generated and marked by this site’s own server, so a set of answers is sent back to be scored — there is no sign-up and no account, and nothing is kept once a run is graded.
- What age is this aimed at?
- Primary school arithmetic - the number facts children are expected to recall rather than work out. You tick which numbers from 0 to 12 the first and second numbers are drawn from, so it stretches from early addition up to the 12 times table.
- Should I use a time limit?
- Not at first. Accuracy comes before speed, and a timer on a child who is still working the answers out teaches anxiety rather than arithmetic. Add it once the facts are known and you want recall to become automatic.
- Is there an account or any record kept?
- No account, and no record. Results are shown at the end of a run and then gone - nothing is stored, and nobody is tracked from one session to the next.
- Where does the marking happen?
- Unlike most tools on this site, this one uses the server: the problems are generated and the answers are marked by an API on johnmcm.com, so a set of answers is sent there to be scored. Nothing is written down or kept once the run is graded.
- Why 10, 25, 50 or 100 problems?
- Ten for a quick check, twenty-five for a normal practice session, and the longer sets for building stamina. A short set done daily beats a long one done occasionally.
