Free addition and subtraction game for Years 1 to 6 — numbers to 20, 100 and 1,000, matched to the national curriculum. No account needed.
Choose a number range and practise connected mental addition and subtraction questions with immediate corrective feedback. 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: Develop fluent mental addition and subtraction and use inverse relationships to check answers.
Curriculum anchor: England mathematics programmes of study: number, addition and subtraction across Key Stages 1 and 2.
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.
Ask which number fact made the answer easier, such as bridging through ten or using a known inverse. 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.
