Free multiples, factors, primes and square numbers game for Years 4 to 6, matched to the national curriculum. No account needed.
Choose multiples, factors, prime numbers or square numbers and practise identifying each property. 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: Recognise multiples, factors, prime numbers and square numbers and use their defining properties.
Curriculum anchor: England mathematics programmes of study: number, multiplication and division in upper Key Stage 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 for the definition that proves each answer rather than accepting a remembered label alone. 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.
