Free Year 9 Maths practice — reason with bounds, indices, surds, factors and recurring decimals. No account needed.
Use rounding intervals, exact-number forms, prime-factor reasoning and recurring-decimal conversions. 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: Keep exact and rounded values distinct while applying index, surd, divisibility and recurrence rules precisely.
Curriculum anchor: England KS3 Mathematics: rounding and bounds; integer, fractional and negative powers; real roots; surds; prime factors; recurring decimals.
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 whether the value is exact or rounded, which endpoint is excluded and which algebraic rule justifies each step. 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.
