Free doubling and halving game for Years 1 to 4, matched to the national curriculum. No account needed.
Practise connected doubling and halving facts with ranges to 20, 50 and 100. The default practice mode is untimed, so the learner can think before choosing. Correct answers build a gentle celebration; mistakes receive corrective feedback and return later rather than causing a penalty spiral.
Learning objective: Recall doubles and corresponding halves, using the inverse relationship between multiplication and division.
Curriculum anchor: England mathematics programmes of study: multiplication and division, mental calculation and inverse operations.
This game is designed as short independent practice after an idea has been introduced. It does not replace direct teaching, mathematical or scientific discussion, or an adult checking whether the learner can explain the idea away from the screen.
Pair each double with its matching half and ask what stays the same when the number range increases. Stop while attention is still good. A short accurate return tomorrow is more useful than extending a tired session today.
Does it need an account? No. The game runs in the browser and asks for no name, email address, school or location.
Is it timed? Practice is untimed. Where a sprint exists it is optional. Times Tables Sprint also includes MTC-style independent practice, not an expected-standard judgement.
Can it be used on a phone? Yes. Buttons support touch and keyboard use; sorting always has a tap alternative to dragging.
