Number Time
Arithmetic, fractions, decimals, percentages and multi-step word problems — every question is generated fresh and tuned to your child's year group, so it never feels too easy or too hard for long.
What's covered, year by year
- Years 1–3: number sense, addition & subtraction, times tables, early fractions.
- Years 3–4: fractions, decimals, division with remainders, multi-step word problems.
- Years 5–6: percentages, ratio, algebraic reasoning, and 11+-style problem solving.

To change a fraction to a percentage, write it as an equivalent fraction out of 100: 3/4 = 75/100, so 3/4 = 75%.
Sam buys 3 pens at £0.75 each and a ruler for £0.50. He pays with a £5 note. How much change does he get?
- £2.25 ✓
- £2.75
- £4.25
- £3.75
The pens cost 3 × £0.75 = £2.25. With the ruler the total is £2.25 + £0.50 = £2.75. Change = £5 − £2.75 = £2.25.
Division with remainders
What is 59 ÷ 7?
- 8 r 3
- 8 r 4
- 7 r 10
- 9 r 3
Nailed it!
8 × 7 = 56. 59 − 56 = 3 left over. So 59 ÷ 7 = 8 remainder 3.

How the difficulty adapts
Number Time, tuned question by question
Nothing about Number Time’s difficulty is fixed. It’s read from a live ability rating that moves with every answer, anchored to your child’s school year, and only ever called "secure" once the evidence backs it up.
A live ability rating
Every question quietly moves a maths rating (an Elo/IRT-style model, starting around 800) up when your child clears something harder than their current level, and eases it back after a run of misses — so the next question keeps landing right at the edge of what they can do.
Year-anchored, then placed
A brand-new Number Time trail doesn't start from nothing: it cold-starts near the standard expected for their school year, then a short placement run of questions settles the exact level within the first few answers.
The same score you see as a parent
That rating is what becomes the 55–145 standardised-style score on the parent dashboard, centred on 100 like an 11+ standardised score — a useful guide, not an official result.
Stretched, not overwhelmed
Number Time is capped to roughly one depth tier past what's already secure — never a whole year ahead into shaky ground — while still looping back through number, fractions, ratio, geometry and statistics so no domain gets left behind.
Learned things come back
Once a topic like times tables or converting fractions to percentages is secure, it resurfaces on its own spaced schedule — often at first, further apart the longer it sticks — so it stays automatic instead of fading.
Five domains, one score today
Under the hood, every question is already tagged to one of five National Curriculum domains — Number & Operations, Fractions/Decimals/Percentages, Ratio & Algebra, Geometry & Measurement, Statistics. Today they still share one Number Time rating; a separate rating per domain is the groundwork already laid for what comes next.
The same five-stage scale every subject's trail runs on — Number Time's rating moves along it as your child answers.
The rating a typical child is expected to be secure at, by the end of each school year — about 250 points per year.
