SATs-aligned maths practice,
powered by real exam data.
Generate unlimited arithmetic and reasoning questions that mirror the real KS2 SATs papers. Explore years of exam analytics to find exactly where your pupils need practice.
Mirror the real KS2 Paper 1 — choose from 26 question types across fractions, long division, percentages, BODMAS, and more. Every question is seeded for exact reproduction.
Our 3-layer engine produces realistic word problems: a Mathematical Kernel generates numbers, the Semantic Bridge validates context, and the Context Skin dresses them in natural language. No nonsensical questions — ever.
Explore every question from 8 years of KS2 SATs papers. Filter by year, difficulty, and content domain. See facility ratings, scatter plots, curriculum coverage heatmaps, and time-series trends that reveal exactly how maths is examined.
Plot cognitive complexity against facility to find the hardest question types at a glance.
Radar charts showing performance by strand — spot weaknesses in number, algebra, geometry, and more.
Track how facility changes year-on-year across content domains and question types.
Our reasoning engine separates maths from story. One set of numbers, infinite word problems.
Generates pure number relationships — division with remainders, fractions, percentages — and tags each output with properties like money_safe or has_remainder.
Reads the kernel's tags and filters out invalid contexts. Recurring decimal? Block money. Fractional result? Block discrete items. No nonsensical questions.
Dresses valid numbers in a narrative template — eggs in boxes, ribbon cutting, discount calculations. The same maths produces completely different word problems.
